They are widely used by numerous research institutions and bioengineering companies.
[0003] Currently, in existing technologies, 96-well plates have 96 wells. When using them, reagents are added to each well. However, during the reagent addition process, due to the poor isolation between each well, cross-contamination can easily occur during shaking or centrifugation, which in turn affects the accuracy of the test results. Therefore, there is a need to propose a 96-well plate that prevents cross-contamination. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a 96-well plate for preventing cross-contamination. (See also...) Figures 1-5 A 96-well plate for preventing cross-contamination includes a base plate 1, a clamping plate 2 inside the base plate 1, a sample tube 21 inside the clamping plate 2, a cover plate 4 on the top of the base plate 1, and a sealing mechanism 3 on the top of the inner wall of the cover plate 4. By introducing cell reagent into the sample tube 21, the clamping plate 2 and the sample tube 21 are stably inserted into the inner cavity of the base plate 1. The cover plate 4 is placed on top of the base plate 1, and the sealing mechanism 3 blocks the port of the sample tube 21, so that the cell reagent in the sample tube 21 will not overflow. Therefore, the cell reagent inside the sample tube 21 will not overflow during shaking and centrifugation, thus preventing cross-contamination. The sealing mechanism 3 includes a positioning rod 31, which is fixedly connected to the top of the inner wall of the cover plate 4. A plug 32 is slidably connected to the outer wall of the positioning rod 31. A sealing groove 34 is provided at the bottom of the plug 32, and a sealing ring 35 is provided in the sealing groove 34. The sealing ring 35 contacts the top of the placement tube 21. A rubber pad 33 is provided at the top of the plug 32, and the rubber pad 33 is slidably connected to the outer wall of the positioning rod 31. An outer edge 36 is provided at the bottom of the plug 32, and the outer edge 36 is inclined outward. By covering the cover plate 4 on top of the base plate 1, the positioning mechanism is achieved. The plug 32 on the rod 31 is engaged at the port of the sample tube 21. The inclined outer edge 36 can improve the fault tolerance of the connection between the plug 32 and the port of the sample tube 21. The rubber pad 33 above the plug 32 cooperates to abut against the plug 32 to improve the tightness of the contact between the plug 32 and the port of the sample tube 21, so that the plug 32 and the sample tube 21 can be sealed. The sealing ring 35 in the sealing groove 34 abuts against the port of the sample tube 21 to prevent the cell reagent in the sample tube 21 from overflowing, thus achieving the purpose of the plug 32 blocking the port of the sample tube 21.
[0018] Reference Figure 1 , Figure 3 and Figure 5The base plate 1 has a side groove 15 on its outer side, and the cover plate 4 is inserted into the outside of the side groove 15. A positioning plate 11 is fixedly connected to one side of the base plate 1, and a positioning groove 41 is opened on one side of the cover plate 4. The positioning plate 11 and the positioning groove 41 are inserted into each other. A circular groove 13 is opened at the bottom of the through groove 12. One end of the placement tube 21 passes through the bottom of the clamping plate 2 and extends into the inside of the circular groove 13. A slot 14 is opened on both sides of the through groove 12, and a locking block 22 is fixedly connected to both sides of the clamping plate 2. The locking block 22 is inserted into the inside of the slot 14 and passes through the edge of the cover plate 4. The cover plate 4 is inserted into the side groove 15 of the base plate 1. The cover plate 4 and the base plate 1 can be easily opened and closed through the positioning plate 11 and the positioning groove 41. The clamping plate 2 is inserted into the through groove 12. The bottom of the laying tube 21 extends into the circular groove 13. The clamping block 22 is inserted into the clamping groove 14. The clamping blocks 22 on both sides of the clamping plate 2 can provide a stable force point when the clamping plate 2 is disassembled and assembled, thereby improving the convenience of disassembling and assembling the clamping plate 2 and the laying tube 21. The clamping plate 2 and the laying tube 21 can be disassembled separately for cleaning, which improves the convenience of cleaning the laying tube 21.
[0019] Reference Figure 2 and Figure 4 The outer wall of the positioning rod 31 has a sliding groove 37. One end of the plug 32 is slidably connected to the inside of the sliding groove 37. The inner cavity of the plug 32 has a limiting groove 38. The lower edge of the positioning rod 31 is slidably connected to the inside of the limiting groove 38. The inner cavity of the base plate 1 has a through groove 12. The clamping plate 2 is inserted into the inside of the through groove 12. The plug 32 slides in the sliding groove 37 on the outer wall of the positioning rod 31. The rubber pad 33 cooperates with the plug 32 to improve the tightness of the contact between the plug 32 and the port of the sampling tube 21, so that the plug 32 and the sampling tube 21 can be sealed. The lower edge of the positioning rod 31 cooperates with the limiting groove 38 to make the plug 32 slide stably up and down.
[0020] Working principle: In use, the cell reagent is introduced into the sample tube 21 on the clamp 2. One end of the sample tube 21 extends into the circular groove 13. The cover plate 4 is placed over the sample tube 21 along the side groove 15 of the base plate 1. The sealing mechanism 3 blocks the port of the sample tube 21 to prevent the cell reagent in the sample tube 21 from overflowing during shaking or centrifugation. The plug 32 is engaged with the port of the sample tube 21. The outer edge 36 guides the port of the sample tube 21 to abut against the sealing ring 35 in the sealing groove 34, thereby sealing the port of the sample tube 21. The rubber pad 33 in the sliding groove 37... The plug 32 is pressed against the top, making it in close contact with the sample tube 21. The lower edge of the limiting groove 38 and the positioning rod 31 cooperate with the plug 32 to slide up and down stably, thereby achieving a stable seal at the port of the sample tube 21. The positioning plates 11 on both sides of the base plate 1 cooperate with the positioning grooves 41 on both sides of the cover plate 4 to facilitate the opening and closing of the cover plate 4 and the base plate 1. By pushing the locking block 22 on the clamping plate 2 with a finger, the locking block 22 separates from the locking groove 14, thereby allowing the clamping plate 2 to be easily moved out of the through groove 12, and thus allowing the clamping plate 2 and the sample tube 21 to be easily disassembled and cleaned.
