[0069] Referring to FIG. 7, a plurality of horizontal bars (310) may include a first horizontal bar (311) and a second horizontal bar (312) that are adjacent to each other. Here, the horizontal bars (310) being arranged adjacent to each other may mean that they are arranged in the adjacent fixing holes (15a, 16a) among the first and second fixing holes (15a, 16a).

[0070] As previously explained with reference to FIGS. 3 to 5, a plurality of holders (320) can move horizontally on a corresponding horizontal bar (310). Additionally, a hook portion (330) is rotatably coupled to a holder (320) and can rotate 360 ​​degrees in a direction perpendicular to the direction in which the holder (320) is extended (e.g., the front direction).

[0071] A first holder (321) placed on a first horizontal bar (311) and a second holder (322) placed on a second horizontal bar (312) may be placed in the same row (i.e., the same vertical position). A first hook portion (331) and a second hook portion (332) may be attached to the first holder (321) of the first horizontal bar (311) and the second holder (322) of the second horizontal bar (312), respectively, that are adjacent to each other. The first hook portion (331) of the first holder (321) of the first horizontal bar (311) and the second hook portion (332) of the second holder (322) of the second horizontal bar (312) may be fastened together to form a single second circular mounting portion (OR2). The second circular mounting part (OR2) can be positioned vertically with respect to the bottom plate (14, FIG. 1) of the main body (10).

[0072] In one embodiment, the central mounting portion (300) may be provided with a plurality of second circular mounting portions (OR2). The second circular mounting portions (OR2) aligned in the same row (i.e., the same horizontal position) can mount experimental equipment (e.g., a pipette, P) in a horizontal direction.

[0073] The experimental equipment stand (1) according to the present invention comprises holders (320) that are horizontally movable with respect to a horizontal bar (310), and first hook portions (331) and second hook portions (332) that are rotatably coupled to adjacent holders (320), so that experimental equipment (e.g., pipettes, P) can be vertically and / or horizontally mounted using one experimental equipment stand (1).

[0074] FIG. 8 is a drawing showing a length adjustment part of a holder according to one embodiment. FIG. 9 is a cross-sectional view showing a length adjustment part of a holder according to one embodiment. FIG. 10 is a drawing showing a state in which experimental instruments are vertically mounted on some holders in an experimental instrument stand according to one embodiment.

[0075] Referring to FIGS. 8 and 9, a plurality of holders (320) may be adjustable in length in one direction (e.g., direction E). The direction E may be the same as the direction in which the plurality of holders (320) are extended. Each of the plurality of holders (320) may include an end (320P0) having through holes (320a) through which a horizontal bar (310) passes, and a length adjustment part. In one embodiment, the plurality of holders (320) may be adjustable in length in three stages, and the length adjustment part of each of the plurality of holders (320) may include a first length adjustment part (320P1), a second length adjustment part (320P2), and a third length adjustment part (320P3). However, the present invention is not limited thereto, and the plurality of holders (320) may be adjustable in length in two stages or four stages or more.

[0076] FIGS. 8 and 9 illustrate a holder (320') with a length extended within a possible range in the E direction. One end of the first length adjustment part (320P1) of the length-extended holder (320') may be coupled to or integrally formed with the end (320P0) of the holder (320'). One end of the second length adjustment part (320P2) of the length-extended holder (320') may overlap with at least a portion of the other end of the first length adjustment part (320P1). The other end of the first length adjustment part (320P1) may include a first joining means (CT1). One end of the second length adjustment part (320P2) may include a second joining means (CT2). The first joining means (CT1) and the second joining means (CT2) can meet each other at the portion where one end of the second length adjustment part (320P2) and the other end of the first length adjustment part (320P1) overlap. When the first joining means (CT1) and the second joining means (CT2) meet, they are joined to each other, which can prevent the second length adjustment part (320P2) from detaching from the first length adjustment part (320P1). For example, the first joining means (CT1) and the second joining means (CT2) may be magnets having opposite polarities. In this case, the first joining means (CT1) and the second joining means (CT2) can be joined by magnetic force.

[0077] Similarly, one end of the third length adjustment part (320P3) may overlap with at least a portion of the other end of the second length adjustment part (320P2). The other end of the second length adjustment part (320P2) may include a third joining means (CT3). One end of the third length adjustment part (320P3) may include a fourth joining means (CT4). The third joining means (CT3) and the fourth joining means (CT1-4) may meet each other at the portion where the other end of the third length adjustment part (320P3) and the one end of the third length adjustment part (320P3) overlap. When the third joining means (CT3) and the fourth joining means (CT4) meet, they may be joined to each other to prevent the third length adjustment part (320P3) from detaching from the second length adjustment part (320P2). For example, the third joining means (CT3) and the fourth joining means (CT4) may be magnets having opposite polarities. In this case, the third joining means (CT3) and the fourth joining means (CT4) may be joined by magnetic force.

[0078] FIG. 10 illustrates first circular mounting parts (OP1) coupled to holders (320) that are not extended in length and first circular mounting parts (OP1) coupled to holders (320') that are extended in length. A first experimental apparatus (P1) can be vertically mounted on the first circular mounting parts (OP1) coupled to holders (320) that are not extended in length. A second experimental apparatus (P2) can be vertically mounted on the first circular mounting parts (OP1) coupled to holders (320') that are extended in length. The first experimental apparatus (P1) and the second experimental apparatus (P2) can be spaced apart from each other in the horizontal direction and the front direction (or rear direction). The first through hole (21a-1) and the second through hole (21a-2) of the mounting plate (21) respectively accommodate the end of the first experimental apparatus (P1) and the end of the second experimental apparatus (P2), and these first through hole (21a-1) and second through hole (21a-2) can be arranged in different rows and columns on the mounting plate (21).

[0079] According to the experimental equipment stand (1) of the present invention, since the lengths of the plurality of holders (320) can be adjusted, multiple experimental equipment can be stably mounted at a distance from each other. In addition, one experimental equipment can be mounted horizontally on a single experimental equipment stand (1) while another experimental equipment can be mounted vertically.

[0080] FIG. 11 is a cross-sectional view showing a lower unit of an experimental equipment stand according to one embodiment, showing a cross-section along line A-A' of FIG. 1. Also, FIG. 12 is a cross-sectional view showing a mounting plate of an experimental equipment stand according to one embodiment.

[0081] Referring to FIGS. 11 and 12, the lower unit (20) may include a mounting plate (21), a base plate (22), and a support plate (23). The mounting plate (21) may be provided in the shape of a disc. The mounting plate (21) may include a plurality of through holes (21a). The plurality of through holes (21a) may be arranged in a plurality of rows and columns on the mounting plate (21). The plurality of through holes (21a) may be formed by penetrating the upper and lower surfaces of the mounting plate (21).

[0082] Multiple through holes (21a) may be formed through the upper and lower surfaces of the mounting plate (21) to have different diameters. Alternatively, the inner surface of the multiple through holes (21a) may be provided as an inclined surface having a downward angle of inclination. Accordingly, each of the multiple through holes (21a) can accommodate and mount the ends of experimental instruments having various diameters (e.g., tips of pipettes, PT). Additionally, any remaining solution or water after washing on the mounted experimental instruments can be discharged through the multiple through holes (21a).

[0083] A base plate (22) may be placed below a mounting plate (21). The base plate (22) may include a mounting plate (21), a first base plate (22-1), and a second base plate (22-2). The first base plate (22-1) and the second base plate (22-2) may be provided in the shape of a disc. The second base plate (22-2) may be placed between the first base plate (22-1) and the mounting plate (21). The first base plate (22-1) may be placed parallel to the mounting plate (21). The angle (α) of the second base plate (22-2) with respect to the first base plate (22-1) may be 0 to 10 degrees. The angle (α) of the second support plate (22-2) with respect to the first support plate (22-1) may refer to the angle of the upper surface of the second support plate (22-2) with respect to the upper surface of the first support plate (22-1). The second support plate (22-2) may have a downward slope with respect to the mounting plate (21).

[0084] The base plate (22) can be spaced apart from the mounting plate (21) in the vertical direction. Since the second base plate (22-2) is spaced apart from the mounting plate (21) in the vertical direction, the ends of the experimental instruments mounted in the through holes (21a) of the mounting plate (21) can be spaced apart from the second base plate (22-2). Accordingly, the ends of the experimental instruments can be prevented from being contaminated, and the mounted experimental instruments can be easily cleaned and dried. The solution or water discharged from the mounted experimental instruments through the through holes (21a) can move to one side through the inclined second base plate (22-2). Although not illustrated, in one embodiment, a discharge port capable of discharging the solution or water may be provided on the one side of the second base plate (22-2).

[0085] At least a portion of the mounting plate (21) and the base plate (22) of the lower unit (20) may be fixed or joined to each other. In one embodiment, the central portion of each of the mounting plate (21) and the base plate (22) of the lower unit (20) may be fixed or joined through a vertical joining means (20P).

[0086] The support plate (23) may be positioned at the bottom of the base plate (22). The base plate (22) may be rotatably coupled to the support plate (23). The mounting plate (21), coupled to the base plate (22) by a vertical coupling means (20P), may rotate together with the base plate (22). The support plate (23) may be provided in the shape of a disc. The mounting plate (21) and the base plate (22) may rotate about an up-and-down axis with respect to the support plate (23). Accordingly, the main body (10), which is fixed to the mounting plate (21) or the base plate (22) through the fixing rods (211, 221) of the fixing part (200), may rotate with respect to the support plate (23).

[0087] Since the main body (10) of the experimental equipment stand (1) according to the present invention is rotatable, the experimental equipment mounted during the experiment can be used in the appropriate place, thereby improving work efficiency.

[0088] FIG. 13 is a drawing showing additional mounting means for an experimental equipment stand according to one embodiment. FIG. 13 shows the main body (10) of the experimental equipment stand (1) viewed from one side.

[0089] Referring to FIG. 13, separate additional mounting means (400) may be disposed on one side of the main body (10). In one embodiment, additional mounting means (400) may be coupled and disposed on the outer surface (12) of the first fixing part (210) and / or the outer surface (13) of the second fixing part (220). FIG. 13 illustrates, as an example, that additional mounting means (400) are coupled and disposed on the outer surface (13) of the second fixing part (220).

[0090] In one embodiment, the additional mounting means (400) may be a burette clamp. The additional mounting means (400) may include a first grip portion (410) and a second grip portion (420). An experimental instrument, such as a burette, may be mounted between the first grip portion (410) and the second grip portion (420).
