It will be understood by those of ordinary skill in the art from the disclosure herein that other cooling mechanisms can be implemented into the main body 111.

[0048] In one or more embodiments, the sample inlet 112 may extend in one direction from the body 111. An inlet 116 may be formed at an end of the sample inlet 112 to communicate with the inlet 102 of the flask 100. In one or more embodiments, when the condenser 110 is connected to the flask 100, the sample S may be supplied to the flask 100 through the inlet 116, or the target substance evaporated from the flask 100 may flow into the inside of the condenser 110.

[0052] In one or more embodiments, the sample supplier 113 may supply the sample S to the inside of the flask 100. In one or more embodiments, the sample supplier 113 may be connected to the condenser 110, and may supply the sample S to the inside of the flask 100 through the sample inlet 112 of the condenser 110 through the opening 117. For example, when the inlet 102 of the flask 100 is connected to the condenser 110, the sample supplier 113 may supply the sample S to the inside of the flask 100 through the inlet 116 of the condenser 110, and the sample supplier 113 may prevent the sample S from leaking to the outside of the flask 100 and the condenser 110. In one or more embodiments, the sample supplier 113 may include a sample container 1131 in which the sample S is stored, a pipe 1133 extending from the sample container 1131 to the condenser 110, and a sample supply valve 1132 mounted to the pipe 1133 and configured to control a supply flow of the sample S.

[0053] In one or more embodiments, the flask fastening device 130 can automatically fasten the flask 100 to the condenser 110 and separate the flask 100 from the condenser 110. In one or more embodiments, the flask fastening device 130 can be mounted to the sample inlet 112 of the condenser 110. In one or more embodiments, the flask fastening device 130 can grasp the flask 100 and separate the flask 100 from the first position (e.g., Figure 5A The flask 100 is moved from a first position relative to the condenser 110 to a second position where the flask 100 is connected to the condenser 110 (e.g., Figure 5B The flask 100 may be connected to the condenser 110 via the flask connector 231 in the second position. In the first position, the flask 100 may not contact the flask connector 231, and in the second position, the flask 100 may contact the flask connector 231. The gripper 232 may hold the flask 100 in the second position so that the flask 100 may be fastened to the flask connector 231 and connected to the condenser 110. In the second position, the flask 100 may contact the condenser 110, may be connected to the condenser 110, may be fastened to the condenser 110, and so on. In one or more embodiments, when the separation of the target substance is completed, the flask fastening device 130 may move the flask 100 fastened to the condenser 110 from the second position to the first position to separate the flask 100 from the condenser 110. In one or more embodiments, the flask fastening device 130 may rotate the flask 100 around the central axis C while gripping the flask 100. A detailed description of the flask securing device 130 is provided later.

[0054] In one or more embodiments, the flask support device 140 can support the outer surface of the flask 100 (e.g., the bottleneck 101 of the flask 100). In one or more embodiments, the flask support device 140 can move the flask 100 while supporting the flask 100. For example, the flask support device 140 can move the flask 100 to a position where the flask 100 can be grasped by the flask fastening device 130 (e.g., to a first position). In one or more embodiments, the flask support device 140 can be operated to have multi-degree-of-freedom movement (e.g., 6-degree-of-freedom movement, including X, Y, Z, yaw (YAW), pitch (PITCH), and roll (ROLL)), so that the alignment angle and relative position of the flask 100 relative to the flask fastening device 130 are aligned. In one or more embodiments, during the process of fastening and separating the flask 100 to the condenser 110 by the flask fastening device 130, the flask supporting device 140 may move the position of the flask 100 according to the operation of the flask fastening device 130 while supporting the flask 100. In one or more embodiments, the flask supporting device 140 may pivot according to the rotation operation of the flask 100 while supporting the flask 100.

[0055] In one or more embodiments, the support station 150 can support the condenser 110. The support station 150 can adjust the support position of the condenser 110 relative to the ground (e.g., the height of the condenser 110 relative to the ground) or the slope of the condenser 110 relative to the ground (e.g., the tilt angle of the condenser 110 relative to the ground).

[0056] In one or more embodiments, the bath 160 may transfer heat to the flask 100. In one or more embodiments, the bath 160 may accommodate the flask 100. The bath 160 may heat the accommodated flask 100 at a set temperature. In one or more embodiments, the set temperature at which the bath 160 heats the flask 100 may be controlled to be determined depending on the BT of the target substance to be separated from the sample S.

[0057] In one or more embodiments, the table 170 may support the bath 160. In one or more embodiments, the table 170 may adjust the position of the bath 160. For example, the table 170 may adjust the relative position of the bath 160 relative to the flask 100 fastened to the condenser 110 by adjusting the position of the bath 160 on a flat surface parallel to the ground and the height of the bath 160 relative to the ground by the table 170. For example, while the flask 100 is fastened to or separated from the condenser 110, the table 170 may move the bath 160 to a position of the flask 100 outside the bath 160 so as not to interfere with the operation of the flask fastening device 130, and during the heating of the flask 100 fastened to the condenser 110, the table 170 may move the bath 160 to a position to accommodate the flask 100.

[0061] In one or more embodiments, the flask 100 can be supported by a flask supporting device 140. The flask supporting device 140 can move the position of the flask 100 while grasping the outer surface of the flask 100. In one or more embodiments, the flask supporting device 140 can be provided as an articulated robot with multi-degree-of-freedom movement. In one or more embodiments, the flask supporting device 140 can grasp the flask 100 and align the condenser 110 to a position where the flask 100 can be fastened to (i.e., connected to, contacted, etc.) the condenser 110. For example, in a first position, the flask supporting device 140 can be in an aligned state. In one or more embodiments, the first position can be a position where the outer surface of the flask 100 can be grasped by the flask fastening device 130, and the flask 100 can be in the first position (e.g., Figure 5A The second position may be a position to which the flask 100 is pulled and moved by the flask fastening device 130, and the flask 100 may be in the second position (e.g., Figure 5BThe flask 100 may be fastened to the condenser 110 in a first position relative to the condenser 110 (the position of the flask 100 relative to the condenser 110). The flask fastening device 130 may move the flask 100 between a first position and a second position relative to the condenser 110. In the second position, the flask 100 may be connected to the condenser 110 via the flask connector 231. In the first position, the flask 100 may not contact the flask connector 231, and in the second position, the flask 100 may contact the flask connector 231. The gripper 232 may hold the flask 100 in the second position so that the flask 100 may be fastened to the flask connector 231 and connected to the condenser 110. In the second position, the flask 100 may contact the condenser 110, may be connected to the condenser 110, may be fastened to the condenser 110, and so on.

[0062] In one or more embodiments, during the process of fastening the flask 100 to the condenser 110, as the flask 100 moves from the first position to the second position, the flask support device 140 may adjust the position of the flask 100 according to the operation of the flask fastening device 130 while supporting the flask 100. In the second position, the flask 100 may be connected to the condenser 110 via the flask connector 231. In the first position, the flask 100 may not contact the flask connector 231, and in the second position, the flask 100 may contact the flask connector 231. The gripper 232 may hold the flask 100 in the second position so that the flask 100 may be fastened to the flask connector 231 and connected to the condenser 110. In the second position, the flask 100 may contact the condenser 110, may be connected to the condenser 110, may be fastened to the condenser 110, and the like. In one or more embodiments, during the process in which the flask 100 is separated from the condenser 110 and moved from the second position to the first position, the flask support device 140 can move the flask 100 according to the movement operation of the flask fastening device 130 while supporting the flask 100.

[0063] In one or more embodiments, when the flask 100 is fastened to the condenser 110 by the flask fastening device 130 , the flask supporting device 140 may be operated to selectively release the gripping state of the flask 100 so as not to interfere with the heating operation of the flask 100 .

[0064] In one or more embodiments, the condenser 110 may be supported by a support station 150. In one or more embodiments, the support station 150 may include a support 254 on the ground, a height adjuster 253 movably connected to the support 254, a connector 252 rotatably connected to the support 254, an actuator 255 for rotating the connector 252, and a column support 251 for supporting the condenser 110.

[0065] In one or more embodiments, the support 254 may be on the ground and may extend in the height direction h. In one or more embodiments, the height adjuster 253 may be movably connected to the support 254 in the height direction h. For example, a guide rail 2541 may be formed on the support 254 along the height direction h perpendicular to the ground, and the height adjuster 253 may be movably connected to the support 254 along the guide rail 2541. In one or more embodiments, the connector 252 may be connected to the height adjuster 253 and may rotate relative to the support 254 about a first axis A1 parallel to the ground. In one or more embodiments, the column support 251 may be connected to the connector 252. In one or more embodiments, the column support 251 may be formed as a bracket structure, and the condenser 110 may be fixed to the column support 251. In one or more embodiments, the height of the column support 251 from the ground may be changed depending on the moving operation of the height adjuster 253 relative to the support 254 in the height direction h. For example, the height of the condenser 110 supported by the column support 251 can be changed depending on the movement of the height adjuster 253 relative to the support 254 in the height direction h. In one or more embodiments, the column support 251 can be rotated relative to the support 254 around the first axis A1 according to the rotation operation of the connector 252. For example, the tilt state of the condenser 110 supported by the column support 251 relative to the ground can be changed according to the rotation operation of the actuator 255 relative to the support 254 around the first axis A1. In this case, when the flask 100 is fixed to the condenser 110, because the position of the flask 100 changes depending on the position change of the condenser 110, the height and slope of the flask 100 can be easily adjusted. For example, when the flask 100 is heated, the tilt angle of the flask 100 can be adjusted by the operation of the support station 150, so that the bumping phenomenon caused when only a certain part of the sample S in the flask 100 is heated can not occur.

[0066] In one or more embodiments, the bath 160 may heat the flask 100 connected to the condenser 110 at a set temperature. For example, a heating liquid maintained at a set temperature may be contained inside the bath 160, and the bath 160 may contain at least a portion of the flask 100 so that the flask 100 may be immersed in the heating liquid. For example, the bath 160 may heat the flask 100 in a double boiling method. However, the method of heating the flask 100 by the bath 160 is not limited to the aforementioned example.

[0067] In one or more embodiments, the table 170 can support the bath 160. In one or more embodiments, the table 170 can adjust the position of the bath 160. In one or more embodiments, the table 170 may include a bath support 271 for supporting the bath 160, a first movable member 272 connected to the bath support 271 and movable in a height direction h perpendicular to the ground, and a second movable member 273 connected to the bath support 271 and movable on a flat surface parallel to the ground. In one or more embodiments, the second movable member 273 may be movably connected along a first guide rail parallel to the ground. In one or more embodiments, the first movable member 272 may be connected to the second movable member 273 and may be movably connected along a second guide rail, which is along the height direction h of the second movable member 273. In one or more embodiments, the bath support 271 may be on the upper part of the first movable member 272. For another example, the first movable member 272 may be moved along a height direction D4 ( Figure 5A ) moves, the second moving member 273 can move in the direction D3 ( Figure 5A ) is movably connected to the first moving member 272 on the stage 170. In this case, the bath support 271 may be on the upper part of the first moving member 272. In one or more embodiments, the stage 170 may adjust the position of the bath 160 to a position suitable for heating the flask 100. In one or more embodiments, the stage 170 may move the bath 160 to a position where the flask 100 is outside the bath 160, so that in the operations before and after the operation of heating the flask 100, the bath 160 does not interfere with the fastening operation of the flask 100 to the condenser 110 and the separation operation of the flask 100 from the condenser 110, or does not interfere with the moving operation of the flask 100.

[0068] In one or more embodiments, the flask fastening device 130 may automatically fasten the flask 100 to the condenser 110 or detach the flask 100 from the condenser 110. In one or more embodiments, the flask fastening device 130 may be mounted to the sample inlet 112 of the condenser 110.

[0069] Reference Figure 3A , Figure 3B , Figure 3C , Figure 4A and Figure 4B The flask fastening device 130 according to one or more embodiments may include a flask connector 231 , one or more grippers 232 , a moving member 233 , an elastic member 234 , a rotating member 235 , and a rotating actuator 236 .

[0070] In one or more embodiments, the flask connector 231 can be mounted to the sample inlet 112 of the condenser 110. For example, the flask connector 231 can be mounted to the end of the sample inlet 112 where the inlet 116 is formed. In one or more embodiments, the flask connector 231 may include a connector hole 2310 that communicates with the inlet 116. In one or more embodiments, the flask 100 can be fastened to the flask connector 231. For example, the flask connector 231 can be connected to a connector mounted to the flask 100. In one or more embodiments, when the flask 100 is fastened to the flask connector 231, the flask connector 231 can connect the inlet 116 of the condenser 110 with the inlet 102 of the flask 100, so that the inlet 116 of the condenser 110 and the inlet 102 of the flask 100 can be communicated.

[0071] In one or more embodiments, the gripper 232 may be connected to the flask connector 231. In one or more embodiments, a plurality of grippers 232 are provided. The plurality of grippers 232 may be arranged to form equal angles based on the central axis C of the flask connector 231, and may contact different points of the outer surface of the flask 100 with uniform force. For example, Figure 3C As shown, the flask fastening device 130 may include four grippers 232A, 232B, 232C, and 232D. The four grippers 232A, 232B, 232C, and 232D may be arranged to form equal angles of 90 degrees based on the central axis C of the flask connector 231 (e.g., based on the center of the connector hole 2310).

[0072] In one or more embodiments, the plurality of grippers 232 may be rotatably connected to rotate about a rotation axis X. In one or more embodiments, the rotation axis X of each of the plurality of grippers 232 may be on the same flat surface perpendicular to the central axis C of the flask connector 231. In one or more embodiments, the plurality of grippers 232 may each have a single degree of freedom of movement rotatable about each respective rotation axis X. In one or more embodiments, the plurality of grippers 232 may rotate about each rotation axis X in a first rotation direction R1 and in a second rotation direction R2 opposite to the first rotation direction R1.

[0073] In one or more embodiments, when rotated in the first rotational direction R1, the gripper 232 can move the flask 100 from a first position (eg, Figure 4A The flask 100 is shown in the position relative to the flask connector 231) to move to a second position (e.g., Figure 4BThe flask 100 shown is relative to the position of the flask connector 231). As the gripper 232 rotates in the first rotational direction R1, the flask 100 can be fastened to the flask connector 231 in the second position, and the gripper 232 can hold the flask 100 in the second position. In one or more embodiments, when rotating in the second rotational direction R2, the gripper 232 can move the flask 100 from the second position to the first position by pushing the end of the flask 100 away from the flask connector 231, so that the flask 100 does not contact the flask connector 231. As the gripper 232 rotates in the second rotational direction R2, the flask 100 can be separated from the flask connector 231, and the fastening / connection state is released while moving from the second position to the first position. For example, the gripper 232 can perform both the fastening operation of the flask 100 to the flask connector 231 and the separation operation of the flask 100 from the flask connector 231 by only a single degree of freedom rotation operation around the rotation axis.

[0074] In one or more embodiments, the gripper 232 may include a gripping member 2321 and a pushing member 2322. In one or more embodiments, the gripping member 2321 and the pushing member 2322 may rotate integrally around the rotation axis X. The gripping member 2321 and the pushing member 2322 may be connected to maintain a constant shape regardless of the rotation operation of the gripper 232. For example, the gripping member 2321 and the pushing member 2322 may rotate in the same direction around the rotation axis X, and the shape of the gripper 232 may be constantly maintained.

[0075] In one or more embodiments, when rotating in the first rotation direction R1, the gripping member 2321 may grip the circumferential surface 104 of the flask 100 and pull the flask 100 in a direction toward the flask connector 231. In one or more embodiments, the gripping member 2321 may have a shape that is bent to wrap around the outside of the bottleneck 101 of the flask 100. For example, the gripping member 2321 may have a shape that widens outward from the rotation axis X toward the flask 100 and the end is bent inward. In one or more embodiments, the gripping member 2321 may move so that while rotating around the rotation axis X, the gap formed by the end 23211 and the central axis C of the flask connector 231 changes. For example, when rotating in the first rotation direction R1, the gripping member 2321 may support the circumferential surface 104 of the bottleneck 101 of the flask 100 with the end 23211 closer to the central axis C of the flask connector 231. When rotating in the second rotation direction R2 , the gripping member 2321 may release the gripping state of the flask 100 as the end portion 23211 moves further away from the central axis C of the flask connector 231 .

[0076] In one or more embodiments, when rotating in the second rotation direction R2, the pushing member 2322 may contact the end of the flask 100 facing the flask connector 231 (e.g., the circumferential surface 104), and may push the flask 100 away from the flask connector 231. In one or more embodiments, the pushing member 2322 may have a shape that is bent in a direction opposite to the gripping member 2321 based on the rotation axis X. For example, the pushing member 2322 may have a shape that is closer to the central axis C of the flask connector 231 from the rotation axis X and is bent in a direction toward the flask 100 (e.g., Figure 4A ). In one or more embodiments, the pushing member 2322 can move so that the position of the end portion 23222 along the central axis C of the flask connector 231 changes while rotating about the rotation axis X. For example, when rotating in the second rotation direction R2, the pushing member 2322 can push the flask 100 in a direction away from the flask connector 231 as the end portion 23222 moves toward the flask 100. When rotating in the first rotation direction R1, the pushing member 2322 can move in a direction opposite to the flask 100 as the end portion 23222 moves without interfering with the fastening of the flask 100 to the flask connector 231.

[0077] For example, the gripper 232 according to one or more embodiments may release the gripping state of the flask 100 by the gripping member 2321 while pushing the flask 100 through the pushing member 2322 when the gripper 232 rotates in the second rotation direction R2 about the rotation axis X. The gripper 232 may grip the circumferential surface 104 of the flask 100 through the gripping member 2321 and pull the flask 100 to be fastened to the flask connector 231 while moving the pushing member 2322 so as not to contact the flask 100 when the gripper 232 rotates in the first rotation direction R1.

[0078] In one or more embodiments, the moving member 233 may be movably connected to the flask connector 231, and may rotate the gripper 232 about the rotation axis X by a moving operation. In one or more embodiments, the moving member 233 may be connected to wrap around a circumferential surface of the flask connector 231 (e.g., an outer surface of the connector hole 2310). In one or more embodiments, the moving member 233 may be translationally movable in a direction parallel to the central axis C of the flask connector 231. For example, the moving member 233 may be movable in a first moving direction D1 toward the gripper 232 (or flask 100) and a second moving direction D2 opposite to the first moving direction D1.

[0079] In one or more embodiments, the mobile member 233 can apply an external force to the gripper 232 to rotate it by moving relative to the flask connector 231. In one or more embodiments, when moving in the first moving direction D1, the mobile member 233 can contact the pushing member 2322 of the gripper 232, or can be connected to apply power to the pushing member 2322. In one or more embodiments, when moving in the first moving direction D1, the mobile member 233 can apply a torque so that the pushing member 2322 rotates in the second rotation direction R2 around the rotation axis X. In this case, the gripper 232 can be rotated in the second rotation direction R2 by the torque applied to the pushing member 2322 by the mobile member 233. In one or more embodiments, while contacting the gripper 232, the mobile member 233 can limit the rotation of the gripper 232 in the first rotation direction R1. In one or more embodiments, the mobile member 233 can be spaced apart from the gripper 232 (e.g., from the pushing member 2322) while moving in the second moving direction D2. In this case, the rotation of the gripper 232 in the first rotation direction R1 may be permitted.

[0080] In one or more embodiments, when the movable member 233 is directly connected to the pushing member 2322, the movement of the movable member 233 in the first moving direction D1 can cause a rotational torque in the second rotational direction R2 applied to the pushing member 2322, and the movement of the movable member 233 in the second moving direction D2 can cause a rotational torque in the first rotational direction R1 applied to the pushing member 2322.

[0081] In one or more embodiments, the elastic member 234 may be connected to the gripper 232, and may apply elastic force to the gripper 232 so that the gripper 232 rotates in the first rotation direction R1. In one or more embodiments, one side of the elastic member 234 may be connected to the flask connector 231, and the other side of the elastic member 234 may be connected to the gripping member 2321 of the gripper 232. In one or more embodiments, when the gripper 232 rotates in the second rotation direction R2 by the moving member 233, the elastic member 234 may store elastic force according to the increase of the gap between the flask connector 231 and the gripping member 2321. In one or more embodiments, when the restriction of the moving member 233 on rotating the gripper 232 in the first rotation direction R1 is released (for example, when the contact between the moving member 233 and the gripper 232 is released), the elastic member 234 may rotate the gripper 232 in the first rotation direction R1 by pulling the gripping member 2321 in the direction toward the flask connector 231 with a restoring force. For example, each gripper 232 may receive an external force from the moving member 233 and the elastic member 234, and may rotate in two directions R1 and R2 about the rotation axis X. In one or more embodiments, the elastic member 234 may be connected to each of the plurality of grippers 232. Figure 3C As shown, a plurality of elastic members 234A, 234B, 234C, and 234D may be provided corresponding to the plurality of grippers 232A, 232B, 232C, and 232D, respectively.

[0082] In one or more embodiments, the rotating member 235 can rotate the flask connector 231, and the flask 100 fastened to the flask connector 231 can rotate relative to the sample inlet 112 of the condenser 110. In one or more embodiments, the rotating member 235 can connect the sample inlet 112 of the condenser 110 to the flask connector 231. For example, the rotating member 235 can be rotatably connected to the sample inlet 112 based on the central axis C of the flask connector 231. In one or more embodiments, the rotating member 235 can be rotatably mounted to the circumferential surface of the sample inlet 112, and the flask connector 231 can be connected to the rotating member 235 and rotate with the rotating member 235. In one or more embodiments, the rotating member 235 can be connected to the rotary actuator 236, and can receive power from the rotary actuator 236 and rotate. In one or more embodiments, the rotating member 235 can rotate in a third rotational direction R3 around the central axis C of the flask connector 231, and can rotate the flask connector 231. When the flask connector 231 rotates in the third rotation direction R3, the gripper 232 connected to the flask connector 231 and the flask 100 fastened to the flask connector 231 can also rotate in the third rotation direction R3. In this structure, since the flask 100 can be continuously rotated in the third rotation direction R3 while the flask 100 is accommodated and heated by the bath 160, the bumping phenomenon caused when only a certain part of the sample S accommodated in the flask 100 is heated can be reduced or prevented. In one or more embodiments, when the flask 100 rotates according to the rotation operation of the flask connector 231 by the rotating member 235, the flask support device 140 for gripping the flask 100 can be pivoted according to the rotation operation of the flask 100.

[0083] FIG. 5A to FIG. 5D are diagrams each illustrating an operation process of the automatic evaporator system 1 according to one or more embodiments. FIG. 5A to FIG. 5D , a series of operations for extracting a target substance from a sample S by the automatic evaporator system 1 are described.

[0084] like Figure 5A As shown, the automatic evaporator system 1 according to one or more embodiments can support the flask 100 with a flask support device 140. The flask support device 140 can move the flask 100 to a first position where the flask 100 is separated from the condenser 110 while supporting the flask 100. In one or more embodiments, the flask support device 140 can align the position and angle of the flask 100 relative to the condenser 110.

[0085] In one or more embodiments, when the flask 100 is in the first position, the flask securing device 130 can be as follows: Figure 5BThe flask 100 is shown to be grasped and fastened to the condenser 110. In one or more embodiments, the gripper 232 can be rotated in the first rotation direction R1 about each rotation axis X so that the gripping member 2321 grips the outer surface of the flask 100 and pulls the flask 100 to a second position where the flask 100 is fastened to the condenser 110. In the second position, the flask 100 can be connected to the condenser 110 via the flask connector 231. In the first position, the flask 100 may not contact the flask connector 231, and in the second position, the flask 100 may contact the flask connector 231. The gripper 232 can hold the flask 100 in the second position so that the flask 100 can be fastened to the flask connector 231 and connected to the condenser 110. In the second position, the flask 100 may contact the condenser 110, may be connected to the condenser 110, may be fastened to the condenser 110, and so on. In this case, the moving member 233 can move in the second moving direction D2 to allow the gripper 232 to rotate in the first rotation direction R1. In one or more embodiments, when the flask fastening device 130 moves the flask 100 from Figure 5A The first position is moved to Figure 5B When the flask support device 140 is in the second position, the flask support device 140 can maintain the state of supporting the outer surface (i.e., the circumferential surface 104) of the flask 100. In this case, the flask support device 140 can move the position of the flask 100 according to the external force applied to the flask 100 (e.g., the external force applied to the flask 100 by the flask fastening device 130) so as not to interfere with the fastening operation of the flask 100 by the flask fastening device 130.

[0086] In one or more embodiments, when the flask 100 is fastened to the condenser 110, the sample S may be supplied to the inside of the flask 100 through the sample supplier 113. However, before the flask 100 is fixed to the condenser 110, the sample S may be contained in the flask 100. In one or more embodiments, when the sample S is supplied inside the flask 100, the flask 100 may be contained in the bath 160 and may be heated.

[0087] In one or more embodiments, the bath 160 may be configured as follows: Figure 5B As shown, the support station 150 is moved to a position where the flask 100 will be heated. In one or more embodiments, when the bath 160 is supported by the bath support 271, the position of the bath 160 can be adjusted by the operation of the second moving member 273 in a direction parallel to the ground and the operation of the first moving member 272 in a direction perpendicular to the ground to accommodate the flask 100. In one or more embodiments, the relative positions of the flask 100 and the bath 160 can be adjusted by the height adjustment of the condenser 110 according to the operation of the support station 150.

[0088] In one or more embodiments, Figure 5C As shown, when the flask 100 is contained in the bath 160, the flask 100 can rotate in the third rotation direction R3 around the center of its bottleneck 101, or can be tilted in the fourth rotation direction R4 so that the slope relative to the ground changes. For example, the flask 100 can rotate in the third rotation direction R3 according to the rotation operation of the rotating member 235. For example, in response to the angle adjustment of the condenser 110 according to the operation of the support station 150 (for example, the angle adjustment of the condenser 110 centered on the first axis A1 parallel to the ground), the flask 100 can rotate in the fourth rotation direction R4 and can perform a tilting operation. In one or more embodiments, by performing a rotation operation in the third rotation direction R3 and a tilting operation in the fourth rotation direction R4 in the bath 160, the flask 100 can allow the entire sample S contained in the interior to be uniformly heated. In this case, the bumping phenomenon caused when only a certain part is heated can be reduced or prevented.

[0089] In one or more embodiments, the target substance evaporated from the sample S may flow into the condenser 110 and may be condensed inside the condenser 110. The condensed target substance may be extracted by the extractor 120 connected to the condenser 110.

[0090] In one or more embodiments, after the separation of the target substance is completed, when the flask 100 is separated from the condenser 110, the flask fastening device 130 can be as follows: Figure 5D As shown, the flask 100 is pushed from the second position to the first position. For example, while moving in translation along the first moving direction D1, the moving member 233 can apply pressure to the pushing member 2322, and the gripper 232 can be rotated in the second rotation direction R2. When the gripper 232 rotates in the second rotation direction R2, the end of the pushing member 2322 can push the end of the flask 100 (i.e., the circumferential surface 104), and when the gripping member 2321 is away from the outside of the flask 100, the grip of the flask 100 can be released. In this case, while maintaining the state of supporting the outer surface of the flask 100 (i.e., the circumferential surface 104), the flask support device 140 can adjust the position of the flask 100 according to the separation operation, in which the flask 100 is pushed away from the condenser 110 by the gripper 232.

[0091] In this structure, during the process of fastening the flask 100 to the condenser 110 or separating the flask 100 from the condenser 110, since only a translation operation in which the flask 100 is pushed in one direction is performed without an operation such as rotation or tilting of the flask 100, vibration during the process of fastening the flask 100 to the condenser 110 can be reduced or prevented.

[0092] The automatic evaporator system according to one or more embodiments may include: a flask configured to accommodate a sample; a bath configured to accommodate the flask and transfer heat to the flask; a condenser including a sample inlet in which an inlet is formed and configured to receive a target substance evaporated from the flask and condense the received target substance; an extractor connected to the condenser and configured to extract a target substance separated from the sample; and a flask fastening device connected to the sample inlet. In one or more embodiments, the flask fastening device may include: a flask connector mounted to the sample inlet and configured to connect the flask to the inlet when the flask connector is fastened to the flask; and one or more grippers connected to the flask connector and configured to move the flask between a first position and a second position, wherein, in the first position, the flask is separated from the flask connector, and in the second position, the flask is fastened to the flask connector.

[0093] In one or more embodiments, the one or more grippers can rotate about each rotation axis relative to the flask connector in a first rotation direction and a second rotation direction opposite to the first rotation direction. In one or more embodiments, when rotated in the first rotation direction, the gripper can move the flask from the first position to the second position, and when rotated in the second rotation direction, the gripper can move the flask from the second position to the first position.

[0094] In one or more embodiments, the gripper may include: a gripping member configured to rotate about a rotation axis and grip a circumferential surface of the flask when rotating in a first rotation direction; and a pushing member configured to rotate about the rotation axis and push the flask away from the flask connector when rotating in a second rotation direction. In one or more embodiments, the gripping member and the pushing member may rotate integrally about the rotation axis.

[0095] In one or more embodiments, when the gripper rotates about the rotation axis, the end of the gripping member can move so that the distance of the end of the gripping member from the central axis of the flask connector changes, and the end of the pushing member can move so that the distance from the end of the pushing member to the central axis changes.

[0096] In one or more embodiments, the gripper may be provided in plurality, and the plurality of grippers may be arranged to form equal angles with respect to the central axis of the flask connector.

[0097] In one or more embodiments, the flask securing device may further include a moving member that is translationally movable in a direction parallel to a central axis of the flask connector and configured to rotate the gripper about the rotation axis.

[0098] In one or more embodiments, the moving member may apply an external force to the gripper and rotate the gripper in a second rotational direction while moving in a first movement direction toward the flask.

[0099] In one or more embodiments, the moving member may apply an external force to the gripper and rotate the gripper in the first rotational direction while moving in a second movement direction opposite to the first movement direction.

[0100] In one or more embodiments, the flask securing device may further include an elastic member connected to each of the one or more grippers and configured to apply an elastic force to the gripper so that the gripper rotates in the first rotational direction.

[0102] In one or more embodiments, the automatic evaporator system may further include a flask support device configured to support the outer surface of the flask and move the flask. In one or more embodiments, when the flask fastening device moves the position of the flask between the first position and the second position, the flask support device can adjust the position of the flask according to the operation of the flask fastening device.

[0103] In one or more embodiments, the flask support device can pivot according to a rotation operation of the flask while supporting the flask.

[0104] In one or more embodiments, the automatic evaporator system may further include a support station, wherein the support station may include a support on the ground, a column support configured to support the condenser, and a connector configured to connect the support to the column support and rotate the column support relative to the support about a first axis parallel to the ground.

[0105] In one or more embodiments, the support station may further include a height adjuster configured to connect the support member to the column support member and adjust a position of the column support member along a height direction of the support member.

[0106] In one or more embodiments, the automatic evaporator system may further include a table configured to adjust the position of the bath, wherein the table may include a bath support configured to support the bath, a first moving member connected to the bath support and movable on a flat surface parallel to the ground, and a second moving member connected to the bath support and movable in a height direction perpendicular to the ground.

[0107] The flask fastening device configured to fasten the flask to the condenser may include: a flask connector mounted to the condenser and including a connector hole connected to the inlet of the condenser for sample injection; and one or more grippers connected to the flask connector and configured to rotate in two directions around each rotation axis. In one or more embodiments, the one or more grippers can grip the flask to fasten it to the flask connector when rotating around the rotation axis in a first rotation direction, and can separate the flask fastened to the flask connector from the flask connector when rotating around the rotation axis in a second rotation direction opposite to the first rotation direction.

[0108] In one or more embodiments, the gripper may include: a gripping member configured to rotate about a rotation axis and, when rotated in a first rotation direction, move the flask in a direction toward the flask connector with the end contacting the circumferential surface of the bottleneck of the flask; and a pushing member configured to rotate integrally with the gripping member about the rotation axis and, when rotated in a second rotation direction, push the flask away from the flask connector by contacting the end of the bottleneck of the flask.

[0109] In one or more embodiments, the flask fastening device may further include a moving member connected to the flask connector and movable in translation in a first moving direction toward the pushing member and in a second moving direction opposite to the first moving direction. In one or more embodiments, when moving in the first moving direction, the moving member may apply pressure to the pushing member and may cause the gripper to rotate in a second rotational direction.
