Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an incubation module and a fully automated enzyme immunoassay analyzer. Background Technology

[0002] A fully automated enzyme immunoassay analyzer (ELISA) is a clinical testing device primarily used to detect specific antigens or antibodies in biological samples such as blood and urine. The analyzer includes an incubation module, which contains an incubation area and an incubator cap placement area. The incubation area contains multiple open incubators, and the cap placement area is used to stack multiple caps. When a sample needs to be incubated, an incubator cap is taken from the cap placement area and placed on the incubator to provide a suitable incubation environment.

[0003] In related technologies, the top of the incubator cover is equipped with a metal counterweight. The counterweight is used to increase the seal between the incubator cover and the incubator. When the incubator covers are stacked, if there is still condensate water generated during the previous incubation process on the incubator cover, the condensate water will not only contaminate the adjacent incubator covers, but may also cause the counterweight to rust and corrode. Utility Model Content

[0004] The main purpose of this invention is to provide an incubation module and an automated enzyme immunoassay analyzer, which aims to improve incubation efficiency while reducing the generation of condensate during the incubation process and avoiding the risk of corrosion of the incubator cover.

[0005] To achieve the above objectives, the present invention proposes an incubation module, including an incubator cover. The incubation module has a placement area for placing the incubator cover, and the incubator cover includes:

[0006] First cover;

[0007] The second cover is connected to the first cover and together forms an accommodating cavity;

[0008] A counterweight is disposed within the accommodating cavity;

[0009] A heating assembly, comprising a heating element and a conductive structure, wherein the heating element is disposed within the accommodating cavity, the conductive structure is connected to the heating element, and at least a portion of the conductive structure extends outside the accommodating cavity;

[0010] When the incubator is placed over the placement area, the conductive structure can be connected to an external circuit and heat the heating element.

[0011] In one embodiment of the present invention, the first cover has a first surface and a second surface disposed opposite to each other. The first surface is recessed with a groove, and the second surface is also provided with a surrounding plate. The surrounding plate is arranged in a ring shape and surrounds the first surface to form an accommodating groove. The side of the counterweight abuts against the surrounding plate.

[0012] The second cover is connected to the outside of the enclosure and forms the receiving cavity with the receiving groove. When multiple incubator covers are stacked in the placement area, the second cover can be inserted into the groove of the adjacent incubator cover.

[0013] In one embodiment of the present invention, the conductive structure includes two spaced conductive blocks, and the second surface is further provided with a fixing groove, the fixing groove passing through the enclosure and communicating with the receiving groove, and the conductive blocks being disposed in the fixing groove.

[0014] In one embodiment of the present invention, the conductive block has a first end and a second end extending along a first direction, the end of the first end being used to abut against an external circuit, and the second end being connected to the heating element;

[0015] The wall of the fixing groove and the surface of the conductive block cooperate to form a limiting structure, which is used to restrict the movement of the conductive block in the first direction.

[0016] In one embodiment of this utility model, the counterweight is provided with a clearance opening at the position corresponding to the conductive structure;

[0017] And / or, a foolproof structure is formed between the counterweight and the first cover.

[0018] In one embodiment of the present invention, the second surface is further provided with a plurality of mounting grooves, which are spaced apart along the outer periphery of the second surface;

[0019] The incubator cover also includes multiple magnetic components, one of which is disposed in one of the mounting slots.

[0020] In one embodiment of the present invention, the second surface is further provided with a plurality of limiting grooves, each of the limiting grooves including a sealing area and a fixing area connected to each other, the sealing area communicating with the mounting groove, and the fixing area extending to the inner side of the projection range of the second cover body on the surface of the first cover body;

[0021] The incubator cover also includes multiple pressure plates, each pressure plate including a cover sealing part and a fixing part connected together, and one pressure plate is fixed in one of the limiting grooves.

[0022] In one embodiment of this utility model, the incubation module further includes:

[0023] A base is provided in the placement area, and a support platform is provided on the surface of the base for placing the incubator cover.

[0024] Two conductive plates are disposed on opposite sides of the base. Each conductive plate is provided with multiple contact springs, which are spaced apart in the vertical direction. When the incubator cover is placed on the support platform, the conductive structure elastically abuts against the contact springs to make the heating circuit conductive.

[0025] In one embodiment of this utility model, the incubation module further includes a temperature control switch, which is disposed on the support platform.

[0026] This invention also provides a fully automated enzyme immunoassay analyzer, which includes the incubation module described above.

[0027] In this invention, a counterweight is placed within the cavity formed by the first and second covers, and the heating element of the heating assembly is also located within the cavity. A conductive structure is connected to the heating element and partially extends outside the cavity. When the incubator cover is placed in the placement area, the conductive structure can connect to an external circuit to heat the heating element. Since the incubator cover is already heated by the heating assembly when placed in the placement area, it ensures that the incubator cover maintains a high temperature. When incubating samples, placing the incubator cover in the placement area onto the incubator prevents the cover from absorbing too much heat from the incubator due to its lower temperature. This improves incubation efficiency. Furthermore, because the incubator cover is preheated, the temperature difference between the cover and the incubator is effectively reduced, preventing condensation during incubation caused by a large temperature difference. This reduces condensation at its source. Even if a small amount of condensation is generated during the incubation process, the counterweight is encased between the first and second covers, preventing it from coming into contact with the condensation. This effectively solves the problem of rust and corrosion caused by direct contact between the counterweight and condensation due to its placement on the surface, thus improving the reliability and service life of the incubator cover.

[0048] A fully automated enzyme immunoassay analyzer (ELISA) is a clinical testing device primarily used to detect specific antigens or antibodies in biological samples such as blood and urine. The analyzer includes an incubation module, which contains an incubation area and an incubator cap placement area. The incubation area contains multiple open incubators, and the cap placement area is used to stack multiple caps. When sample incubation is required, an incubator cap is picked up from the cap placement area and placed on the incubator to provide a suitable incubation environment. In related technologies, the top of the incubator caps is equipped with a metal counterweight. This counterweight is used to reinforce the caps and improve the seal between the caps and the incubator. When the caps are stacked, if condensation generated during incubation remains on the caps, this condensation can contaminate adjacent caps and may also cause the counterweight to rust and corrode.

[0049] This utility model proposes an incubation module, which includes an incubator cover 100 and a placement area for placing the incubator cover 100.

[0050] Reference Figures 1 to 4 In this embodiment of the invention, the incubator cover 100 includes a first cover 10, a second cover 20, a counterweight 30, and a heating assembly 40. The first cover 10 and the second cover 20 are connected and enclose a receiving cavity. The counterweight 30 is disposed within the receiving cavity. The heating assembly 40 includes a heating element 41 and a conductive structure. The heating element 41 is disposed within the receiving cavity, and the conductive structure is connected to the heating element 41. At least a portion of the conductive structure extends outside the receiving cavity. When the incubator cover 100 is placed in the placement area, the conductive structure can be connected to an external circuit to heat the heating element 41.

[0051] The shapes of the first cover 10 and the second cover 20 are adapted to the shape of the incubator opening. The shapes of the first cover 10 and the second cover 20 can be square, round, triangular or polygonal, etc., as long as the incubator cover 100 can be adapted to the incubator and seal the opening of the incubator. The shapes of the first cover 10 and the second cover 20 are not limited here.

[0052] The first cover 10 and the second cover 20 can be made of insulating and corrosion-resistant plastic materials, such as PC plastic, ABS plastic, PBT plastic, PC / ABS hybrid plastic, etc. By using plastic material for the cover of the incubator cover 100, the incubator cover 100 can be used in humid and corrosive environments. The first cover 10 and the second cover 20 can also be made of metal materials, such as iron, steel, aluminum alloy, iron alloy, stainless steel, etc. The surface of the metal is provided with an insulating and corrosion-resistant material layer. The metal material can improve the structural strength and service life of the first cover 10 and the second cover 20.

[0053] The first cover 10 and the second cover 20 can be detachably connected by screws or clips to facilitate the installation and maintenance of the components inside the accommodating cavity; alternatively, the first cover 10 and the second cover 20 can be fixed into an integral structure by ultrasonic welding or thermofusion to improve the reliability of the connection between the first cover 10 and the second cover 20.

[0054] In one specific embodiment, the first cover 10 and the second cover 20 are connected by snap fasteners. Specifically, the first cover 10 is provided with a plurality of snap fasteners 1311, which are spaced apart along the outer periphery of the enclosure 131. The inner surface of the second cover 20 is provided with a plurality of snap fasteners. The detachable connection between the first cover 10 and the second cover 20 is achieved through the cooperation of the snap fasteners and the snap fasteners 1311. Of course, it is also possible that the first cover 10 is provided with a plurality of snap fasteners and the second cover 20 is provided with a plurality of snap fasteners 1311; this is not limited here.

[0055] The counterweight 30 is shaped to fit the contour of the receiving cavity and is positioned within the cavity to help balance the weight distribution of the entire incubator cover 100. This makes the incubator cover 100 more stable when it is closed onto the incubator. At the same time, the counterweight 30 also increases the weight of the incubator cover 100, thereby ensuring that the incubator cover 100 fits tightly against the opening of the incubator, reducing air leakage in the incubation space and helping to maintain the internal temperature of the incubator.

[0056] The counterweight 30 can be made of metal, such as cast iron or steel. Metal has a high density and is heavy, and can be made into the required shape and size through casting.

[0057] The heating element 41 in the heating assembly 40 can be a heating plate or a heating film. By placing the heating element 41 inside the accommodating cavity, the structure can be made compact, and heat can be concentrated. Compared with exposing the heating element 41 to the outside, heat loss can be reduced. There can be one heating element 41, which can be directly attached to any surface of the counterweight 30. The cost of one heating element 41 is low. Alternatively, there can be two heating elements 41, which can be attached to two opposite surfaces of the counterweight 30. The heating efficiency of two heating elements 41 is higher, and the heat distribution of the incubator cover 100 is more uniform, further reducing the temperature difference.

[0058] By extending a portion of the conductive structure outside the accommodating cavity, the design effectively provides power to the heating element 41 while simultaneously separating the electrical connection from the working area of ​​the heating element 41. This prevents the power supply from being damaged by high temperatures due to proximity to the heating element 41, thus extending the service life of the heating assembly 40. When the incubator cover 100 is located in the placement area, the conductive structure enables the heating circuit to conduct, allowing the heating assembly 40 to preheat the incubator cover 100. This ensures the incubator cover 100 is maintained at a high temperature. When the incubator cover 100 is placed on the incubator in the placement area, it prevents the cover from absorbing too much heat from the incubator due to its lower temperature. This improves incubation efficiency and reduces the temperature difference between the cover 100 and the incubator, preventing condensation caused by a large temperature difference and reducing condensation at its source. Meanwhile, even if a small amount of condensation remains on the incubator lid 100, the heating component 40 can accelerate the evaporation of the condensation, keeping the incubator lid 100 dry. The heating component 40 typically heats the incubator lid 100 to a temperature not exceeding 40°C, thus preventing excessively high temperatures from adversely affecting the incubated samples.

[0059] In this utility model, the counterweight 30 is placed in the accommodating cavity formed by the first cover 10 and the second cover 20, and the heating element 41 of the heating assembly 40 is also placed in the accommodating cavity. The conductive structure is connected to the heating element 41 and partially extends out of the accommodating cavity. When the incubator cover 100 is placed in the placement area, the conductive structure can be connected to the external circuit to heat the heating element 41. Since the incubator cover 100 is heated by the heating component 40 when placed in the placement area, it can be ensured that the incubator cover 100 can be maintained at a high temperature. When the sample needs to be incubated, the incubator cover 100 placed in the placement area can be grasped and closed on the incubator, which can prevent the incubator cover 100 from absorbing too much heat from the incubator due to its low temperature. On the one hand, this improves the incubation efficiency. On the other hand, since the incubator cover 100 has been preheated, it can effectively reduce the temperature difference between the incubator cover 100 and the incubator, avoiding the generation of condensation due to a large temperature difference between the incubator cover 100 and the incubator during the incubation process, thus reducing the generation of condensation at the source. Even if a small amount of condensation is generated during the incubation process, since the counterweight 30 is wrapped between the first cover body 10 and the second cover body 20, it can avoid contact with the condensation. This effectively solves the problem of rust and corrosion caused by direct contact between the counterweight 30 and condensation when it is placed on the surface, thus improving the reliability and service life of the incubator cover 100.

[0060] Please refer to the reference. Figure 3 and Figure 4In one embodiment of the present invention, the first cover 10 has a first surface 11 and a second surface 13 disposed opposite to each other. The first surface 11 is recessed with a groove 111, and the second surface 13 is also protruding with a surrounding plate 131. The surrounding plate 131 is arranged in a ring and surrounds the first surface 11 to form a receiving groove 132. The side of the counterweight 30 abuts against the surrounding plate 131. The second cover 20 is connected to the outside of the surrounding plate 131 and surrounds the receiving groove 132 to form a receiving cavity. When multiple incubator covers 100 are stacked in the placement area, the second cover 20 can be inserted into the groove 111 of the adjacent incubator cover 100.

[0061] In one embodiment of the present invention, the first cover 10 includes a base plate, which includes a first surface 11 and a second surface 13 disposed opposite to each other. The shape of the groove 111 on the first surface 11 is adapted to the shape of the second cover 20, and the groove 111 is slightly wider than the outer periphery of the second cover 20. When multiple incubator covers 100 are stacked, the second cover 20 of the lower incubator cover 100 can be inserted into the groove 111 of the adjacent upper incubator cover 100, thereby reducing the stacking height of the multiple incubator covers 100. The base plate and the surrounding plate 131 of the first cover 10 are integral structures to reduce the number of parts, reduce assembly steps, and ensure the structural strength of the first cover 10. The receiving groove 132 formed by the enclosure 131 is roughly the same as the outer contour of the counterweight 30, so that the inner wall surface of the enclosure 131 can abut and limit the counterweight 30 to prevent the counterweight 30 from shaking in the receiving groove 132, thus ensuring the reliability of fixing the counterweight 30.

[0062] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of the present invention, the conductive structure includes two spaced conductive blocks 43, and the second surface 13 is also provided with a fixing groove 133. The fixing groove 133 penetrates the surrounding plate 131 and communicates with the receiving groove 132. The conductive blocks 43 are disposed in the fixing groove 133.

[0063] In one embodiment of the present invention, the two conductive blocks 43 can be disposed on the same side of the heating element 41, or they can be disposed on two opposite sides of the heating element 41. Figure 3 and Figure 4In the illustrated embodiment, two conductive blocks 43 are respectively disposed on opposite sides of the heating element 41 for connection to an external circuit. The conductive blocks 43 can be made of copper, copper-zinc alloy, etc., to ensure good electrical conductivity, thermal conductivity, and strength, as well as good mechanical properties and ease of processing. The shape of the conductive blocks 43 can be square, cylindrical, etc., and is not limited here. In one embodiment, the conductive blocks 43 are approximately rectangular to ensure structural strength, reduce deformation, and ensure reliable contact. The shape of the fixing groove 133 is adapted to the conductive blocks 43, serving both to fix the conductive blocks 43 and to protect them. Understandably, the length of the conductive blocks 43 is longer than the extension length of the fixing groove 133, so that the conductive blocks 43 can protrude beyond the fixing groove 133 and connect to external electrical components.

[0064] Please refer to the reference. Figure 3 and Figure 4 In one embodiment of the present invention, the conductive block 43 has a first end 431 and a second end 432 extending along a first direction. The end of the first end 431 is arc-shaped and is used to abut against an external circuit. The second end 432 is connected to the heating element 41.

[0065] The wall of the fixing groove 133 and the surface of the conductive block 43 cooperate to form a limiting structure, which is used to restrict the movement of the conductive block 43 in the first direction. Specifically, the limiting structure may have a limiting protrusion 433 on the wall of the fixing groove 133 and a limiting groove 1331 on the surface of the conductive block 43; or, the limiting structure may also have a limiting groove on the wall of the fixing groove 133 and a limiting protrusion on the surface of the conductive block 43. The extension of the limiting protrusion 433 is set at an angle to the first direction, and the limiting protrusion 433 is inserted into the limiting groove 1331 to restrict the movement of the conductive block 43 in the first direction. In one embodiment of the present invention, the first direction is the length direction of the conductive block 43. By setting the first end 431 of the conductive block 43 in the length direction as an arc-shaped structure, the first end 431 of the conductive block 43 in the length direction is convex. The arc-shaped structure has a more concentrated contact pressure than the planar structure, so that the contact surface between the conductive block 43 and the contact spring 221 of the charging plate is tightly fitted, avoiding the problem of poor contact due to insufficient contact pressure. The second end 432 of the conductive block 43 in the length direction extends into the accommodating cavity and contacts the heating element 41. It can be understood that the conductive element can directly contact the heating element 41, or it can indirectly contact it through other conductive components, which is not limited here.

[0066] To improve the reliability of the conductive component's fixation and ensure the reliability of the heating circuit connection, limiting protrusions 433 and limiting grooves 1331 are respectively provided on the wall of the fixing groove 133 and the surface of the conductive component. This restricts the sliding of the conductive block 43 within the fixing groove 133, ensuring stable contact between the conductive block 43, the heating component 41, and the external circuit. The limiting protrusions 433 can be located on the conductive block 43, in which case the limiting grooves 1331 are located on the wall of the fixing groove 133; alternatively, the limiting grooves 1331 can be located on the conductive block 43, in which case the limiting protrusions 433 are correspondingly located on the wall of the fixing groove 133. The limiting protrusions 433 and the limiting grooves 1331 can cooperate to achieve the limiting effect.

[0067] It should be noted that the extension of the limiting protrusion 433 at an angle to the first direction means that the extension direction of the limiting protrusion 433 is not parallel to the length direction of the conductive block 43. For example, the limiting protrusion 433 can extend along the width direction or the thickness direction of the conductive block 43, and the position of the limiting groove 1331 corresponds to the limiting protrusion 433. Figure 4 Both sides of the conductive block 43 along its length are provided with limiting protrusions 433 that protrude in the width direction. Correspondingly, the two opposite groove walls of the fixing groove 133 are recessed to form limiting grooves 1331. Through the cooperation of the limiting protrusions 433 and the limiting grooves 1331, the conductive block 43 can be limited, thereby improving the reliability of its fixation.

[0068] Reference Figure 4 In one embodiment of this utility model, the counterweight 30 is provided with a clearance opening 31 at the position corresponding to the conductive structure. The clearance opening 31 can provide clearance space for the conductive structure, which facilitates the installation of the conductive structure.

[0069] In another embodiment, a foolproof structure is formed between the counterweight 30 and the first cover 10. The foolproof structure may be a positioning hole formed on the surface of the counterweight 30, a positioning post protruding from the surface of the first cover 10, or a positioning groove formed on the surface of the counterweight 30, a positioning block protruding from the surface of the first cover 10, etc. By setting the foolproof structure, on the one hand, quick installation and positioning can be achieved during the assembly process to prevent incorrect installation and misinstallation, and on the other hand, the movement of the counterweight 30 relative to the first cover 10 can be restricted after installation.

[0070] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the second surface 13 is further provided with a plurality of mounting grooves 134, which are spaced apart along the outer periphery of the second surface 13; the incubator cover 100 also includes a plurality of magnetic elements 50, and a magnetic element 50 is provided in one mounting groove 134.

[0071] In one embodiment of the present invention, the mounting groove 134 is used to fix the magnetic component 50, so that when the incubator cover 100 is placed on the incubator, the magnetic component 50 attracts the incubator cover 100 to the incubator, thereby generating a magnetic attraction force between the incubator cover 100 and the incubator, which can better hold the incubator cover 100 and allow it to fit better above the incubator opening. It should be noted that the number of mounting grooves 134 and magnetic components 50 is the same. The number of magnetic components 50 can be four, respectively arranged near multiple corners of the outer periphery of the first cover 10, so that when the incubator cover 100 is fitted with the incubator, it can receive attraction forces in four directions, maintaining a balanced force. Of course, the number of magnetic components 50 can also be six, eight, etc., evenly distributed along the outer periphery of the first cover 10, and is not limited here.

[0072] Reference Figure 1 and Figure 4 In one embodiment of the present invention, the second surface 13 is further provided with a plurality of limiting grooves 135, each limiting groove 135 including a cover sealing area 1351 and a fixing area 1353 connected to each other. The cover sealing area 1351 is connected to the mounting groove 134, and the fixing area 1353 extends to the inner side of the projection range of the second cover 20 on the surface of the first cover 10.

[0073] The incubator cover 100 also includes a plurality of pressure plates 60, each pressure plate 60 including a cover sealing part 61 and a fixing part 63 connected to each other, and a pressure plate 60 is fixed in a limiting groove 135.

[0074] In one embodiment of the present invention, a pressure plate 60 is used to press and fix the magnetic component 50 to prevent it from detaching from the mounting groove 134. The pressure plate 60 is designed to include a cover portion 61 and a fixing portion 63. The cover portion 61 abuts against the magnetic component 50, thereby preventing it from falling out of the mounting groove 134. It is understood that the pressure plate 60 can be fixed to the limiting groove 135 through an interference fit, or by using the fixing portion 63 and the fixing area 1353 through thermoforming or ultrasonic welding. In one embodiment, the fixing portion 63 further extends to the inside of the projection range of the second cover 20 onto the surface of the first cover 10. Thus, when the second cover 20 is connected to the first cover 10, the second cover 20 abuts against the second surface 13 of the first cover 10, and the second cover 20 also presses the pressure plate 60 into the limiting groove 135, further improving the reliability of the pressure plate 60 fixation, thereby improving the reliability of the magnetic component fixation.

[0075] Reference Figures 5 to 7In one embodiment of this utility model, the placement area of ​​the incubation module is further provided with a base 210 and two conductive plates 220. The surface of the base 210 is provided with a support platform 211, which is used to place the incubator cover 100. The two conductive plates 220 are located on opposite sides of the base 210. Each conductive plate 220 is provided with a plurality of contact springs 221. The plurality of contact springs 221 are spaced apart in the vertical direction. When the incubator cover 100 is placed on the support platform 211, the conductive structure elastically abuts against the contact springs 221 to make the heating circuit conduct.

[0076] In one embodiment of the present invention, the placement area of ​​the incubation module is used to place an incubator cover 100 that is not currently in use. The placement area is provided with a base 210, and the surface of the base 210 is provided with a support platform 211. The outer periphery of the top of the support platform 211 is similar to the contour of the groove 111, allowing the support platform 211 to extend into the groove 111 of the adjacent incubator cover 100, thereby supporting and fixing the incubator cover 100. Two conductive plates 220 are disposed on opposite sides of the base 210. The conductive plates 220 can be mounted and fixed using a mounting base 230. The mounting base 230 has an installation space facing one side of the base 210 to facilitate the fixing and protection of the conductive plates 220. The conductive plates 220 are provided with elastic contact pieces. When the incubator cover 100 is placed in the placement area, the conductive structure abuts against the elastic contact pieces, thereby conducting the heating circuit. It should be noted that when multiple incubator covers 100 are stacked in the placement area, they can be powered on and heated simultaneously. That is, the incubator covers 100 are automatically heated when placed in the placement area, and multiple incubator covers 100 are heated at the same time.

[0077] The incubation module provides a suitable incubation environment for the samples to ensure that the reaction can proceed efficiently and accurately. The incubation module also has an incubation area with multiple incubators. Each incubator has an open incubation position. When a carrier containing a sample (e.g., a microplate) needs to be placed in an incubator position for incubation, a robotic arm picks up the carrier and places it in the incubation position. Then, the robotic arm picks up the incubator cover 100 from the incubator cover placement area and places it on the incubation position, providing a relatively sealed space for the incubation process.

[0078] Reference Figure 7 In one embodiment of this utility model, the incubation module further includes a temperature control switch 240, which is disposed on the support platform 211 and can contact the incubator cover 100. In this embodiment of the technical solution, when the temperature control switch 240 detects that the heating temperature of the incubator cover 100 is too high, it can control the heating circuit to cut off to avoid the incubator cover 100 from overheating. By setting the temperature control switch 240, the heating temperature of the incubator cover 100 can be precisely controlled, improving the flexibility of the incubation module.

[0079] This utility model also proposes a fully automated enzyme immunoassay analyzer, which includes an incubation module. Since this fully automated enzyme immunoassay analyzer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0080] A fully automated enzyme immunoassay analyzer is a clinical testing device mainly used to detect specific antigens or antibodies in biological samples such as blood and urine. The incubation module is a crucial part of the instrument, and its main function is to provide a suitable environment for the enzyme-linked immunosorbent assay (ELISA) reaction, ensuring that the reaction can be carried out efficiently and accurately.
