Technical Field

[0001] The utility model relates to the technical field of PCR reaction reagent freeze-drying plates, and particularly relates to a high-throughput PCR reaction reagent freeze-drying plate. Background Technique

[0002] ‌PCR reaction reagent freeze-drying‌ is a method for treating PCR reaction reagents through freeze-drying technology. This method involves pre-cooling and freezing the PCR reaction reagents into solids, and then under vacuum conditions, through sublimation, more than 95% of the water is evaporated. At the same time, the protective agent acts as a solidifying agent and will not collapse during sublimation, ensuring the morphology of the freeze-dried products. When performing freeze-drying, the PCR reaction reagents are stored in reagent tubes, and the reagent tubes are placed on the freeze-drying rack;

[0003] For example, the Chinese authorized patent (reagent rack) with the publication number CN205797263U: includes a cabinet body, a column, and a panel. The column is detachably installed on the cabinet body. Threaded holes are opened on the column, and through holes corresponding to the threaded holes are respectively opened on both sides of the panel. Baffles are provided on the periphery of the panel, and both sides of the panel are respectively threadedly connected to adjacent columns through screws. The beneficial effect of the utility model is that it can stably place reagent bottles and protect the cleanliness of the reagent bottles.

[0004] However, when taking the reagent tubes on the existing freeze-drying rack, they need to be taken one by one, which is time-consuming and laborious. And when taking them independently, the cover plate of the freeze-drying rack needs to be pulled, which will cause the top openings of multiple reagent tubes to leak out, thus affecting the freeze-drying effect; Therefore, it does not meet the existing requirements, and for this reason, we propose a high-throughput PCR reaction reagent freeze-drying plate. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-throughput PCR reaction reagent freeze-drying plate to solve the problems in the above-mentioned background technique that when taking the reagent tubes on the existing freeze-drying rack, they need to be taken one by one, which is time-consuming and laborious, and when taking them independently, the cover plate of the freeze-drying rack needs to be pulled, which will cause the top openings of multiple reagent tubes to leak out, thus affecting the freeze-drying effect.

[0011] Preferably, handles are arranged on both side surfaces of the freeze-drying rack body, and the handles are fixedly heat-melted to the freeze-drying rack body.

[0012] Preferably, the outer circle of the top end is inserted into the limiting groove, and the tube body of the test tube moves along the moving groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] Insert the tube body 13 containing the PCR reaction reagent into the test tube slot 2. After arranging a row, fix the installation component 6 from one side of the top outer ring 15. Insert the top outer ring 15 into the limit slot 10 to limit and fix the top outer ring 15, thus connecting the material storage component 5 and the installation component 6. When it is necessary to remove the material storage component 5, directly lift the installation component 6 upward, and then a row of material storage components 5 can be taken out. Then, according to the needs, select the material storage component 5 at the corresponding position and move the material storage component 5 along the opening of the limit slot 10 to separate the material storage component 5 from the installation component 6. In this way, the independent taking of the material storage component 5 is realized, and the phenomenon of leakage from the top opening of other material storage components 5 will not occur, improving the freeze-drying effect.

[0024] Please refer to Figure 2 、 3 On the upper surface of the corner of the upper top plate 7, there is a screw safety groove 16. Inside the screw safety groove 16, there is a fixing screw 12, and one end of the fixing screw 12 passes through the upper top plate 7 and the center plate 8 and is threadedly fixed to the lower bottom plate 9, realizing the separable disassembly of the upper top plate 7, the center plate 8, and the lower bottom plate 9. Frequently fixing the top outer ring 15 through the friction effect is likely to cause wear and needs to be replaced. By replacing it in a separable disassembly manner, it is convenient to reduce the replacement cost.

[0025] Please refer to Figure 1 On the upper surface of each corner of the freeze-drying rack body 1, there is a connection slot 3, and on the lower surface of each corner of the freeze-drying rack body 1, there is a connection leg 4, and the connection leg 4 is heat-melt fixed to the freeze-drying rack body 1. When two freeze-drying rack bodies 1 are freeze-dried together, insert the connection leg 4 of one freeze-drying rack body 1 into the connection slot 3 of the other freeze-drying rack body 1 to realize the splicing of multiple freeze-drying rack bodies 1 for high-throughput freeze-drying operations.

[0027] Working principle: When in use, insert the test tube body 13 filled with PCR reaction reagents into the test tube slot 2. Rely on the release of the limit outer ring 14 from the freeze-drying rack body 1 to limit the test tube body 13 to prevent it from falling. After a row is arranged, fix the installation component 6 from one side of the top outer ring 15. The top outer ring 15 is inserted into the limit slot 10, and the test tube body 13 moves along the moving slot 11. Due to the dimensional difference between the limit slot 10 and the moving slot 11, the top outer ring 15 is limited and fixed, realizing the connection between the material storage component 5 and the installation component 6, and the fixation is achieved through friction. When it is necessary to remove the material storage component 5, directly lift the installation component 6 upward, and then a row of material storage components 5 can be removed. Then, according to the needs, select the material storage component 5 at the corresponding position and move the material storage component 5 along the opening of the limit slot 10, and the separation of the material storage component 5 and the installation component 6 can be realized. In this way, the independent taking of the material storage component 5 is achieved, and the phenomenon of leakage from the top opening of other material storage components 5 will not occur, improving the freeze-drying effect. When two freeze-drying rack bodies 1 are used for freeze-drying together, insert the connecting leg 4 of one freeze-drying rack body 1 into the connecting slot 3 of the other freeze-drying rack body 1 to realize the splicing of multiple freeze-drying rack bodies 1 for high-throughput freeze-drying operation.
