Description

Technical Field

[0001] This utility model relates to the field of experimental consumables technology, specifically to a universal sealing and decompression 96-well plate cover, which is particularly suitable for scenarios in biological and chemical experiments where negative pressure is generated inside the wells after the 96-well plate is sealed. Background Technology

[0002] In biological and chemical experiments, 96-well plates are commonly used experimental instruments for sample storage, reaction, and detection. In many experiments, the 96-well plate needs to be sealed to prevent sample evaporation and contamination. Existing 96-well plate covers have several problems: firstly, the sealing effect is not good, making it difficult to completely prevent sample evaporation and the entry of external impurities, affecting the accuracy of experimental results; secondly, even with a good seal, negative pressure may form inside the wells, affecting sampling and thus the detection results. Currently, 96-well plate covers do not have a pressure-reducing function, failing to address the potential negative pressure problem. Therefore, there is an urgent need to design a 96-well plate cover that can effectively seal, has a pressure-reducing function, and is highly versatile. Utility Model Content

[0022] This utility model embodiment provides a universal sealing and pressure-reducing 96-hole plate cover, such as... Figure 1-5 As shown, the device includes a cover plate body 1, which has a rectangular plate structure and is sized to fit a conventional 96-hole plate. A pressure-reducing chamber 11 is provided inside the cover plate body 1. 96 cover holes 12 are formed at the lower end of the cover plate body 1 corresponding to the 96 holes of the 96-hole plate. The cover holes 12 are vertically continuous and their upper ends communicate with the pressure-reducing chamber 11. The outer diameter of each cover hole 12 is slightly smaller than the inner diameter of the 96 holes of the 96-hole plate to ensure that the cover holes 12 can be smoothly embedded in the 96-hole plate. A pressure-reducing valve 13 is provided in the middle of the upper end of the cover plate body 1. The lower end of the pressure-reducing valve 13 is connected to the pressure-reducing chamber 11. The pressure-reducing valve 13 includes a pressure-reducing pipe 13. 1. A pressure-reducing cap 132 is threaded onto the outer end of a pressure-reducing tube 131. The pressure-reducing tube 131 has several pressure-reducing holes 133 at equal angles around its circumference. The pressure-reducing valve 13 is an adjustable structure. By rotating the pressure-reducing cap 132 on the pressure-reducing valve 13, the opening degree of the pressure-reducing channel can be controlled, thereby adjusting the pressure reduction. When pressure reduction is required in the 96-hole plate, the pressure-reducing cap 132 is opened, and air passes through the cap hole 12 and the pressure-reducing valve 13 to the pressure-reducing channel and is discharged from the pressure-reducing holes 133, thus achieving the purpose of pressure reduction. When pressure reduction is not required, the pressure-reducing cap 132 is closed, restoring the cover plate to a sealed state.

[0023] like Figure 3 As shown, a pre-cut notch 121 is provided at the lower end of the cover hole 12 to facilitate better insertion of the lower end of the cover hole 12 into the hole position of the 96-hole plate. Preferably, a sealing ring 122 is provided on the outer circumference of the cover hole 12 to further improve the sealing performance.

[0024] like Figure 2 and Figure 5 As shown, a sealing groove 14 is formed on the edge of the cover plate body 1, and a sealing ring 15 is installed in the sealing groove 14. The elastic sealing ring 15 is made of elastic materials such as silicone, and its cross-section is trapezoidal. The upper base of the trapezoid is close to the cover plate body 1, and the lower base is away from the cover plate body 1. When the cover plate covers the 96-well plate, the elastic sealing ring 15 is tightly attached to the upper surface of the 96-well plate. The pressure generated by the elastic deformation achieves a good sealing effect, effectively preventing sample volatilization and the entry of external impurities.

[0025] like Figure 4 and Figure 5As shown, adjustable positioning posts are provided on both sides of the cover plate body 1. Each adjustable positioning post includes a fixed part 21 and a movable part 22. The fixed part 21 is fixedly installed on the side of the cover plate body 1, and the movable part 22 is threadedly connected to the fixed part 21. A bearing 23 is connected to the lower end of the movable part 22, and a clamping plate 24 is provided at the lower end of the bearing 23. By rotating the movable part 22, the height of the positioning post can be adjusted so that it can adapt to perforated plates of different thicknesses, ensuring that the cover plate can fit tightly with perforated plates of different specifications.

[0026] Working principle: When using the universal sealing and pressure-reducing 96-hole plate cover, the universal sealing and pressure-reducing 96-hole plate cover is placed on the 96-hole plate. Depending on the thickness of the 96-hole plate, the movable part 22 of the adjustable positioning post is rotated to adjust the height of the positioning post. The clamping block at the lower end of the movable part 22 ensures a tight fit between the cover and the 96-hole plate. At this time, the elastic sealing ring 15 is tightly fitted to the upper surface of the 96-hole plate, achieving a seal. When pressure reduction is required, the pressure-reducing cap 132 of the pressure-reducing valve 13 is rotated to open the pressure-reducing valve 13. Air passes through the cap hole 12 and the pressure-reducing valve 13 to the pressure-reducing channel and is discharged from the pressure-reducing hole 133, achieving the purpose of pressure reduction. When pressure reduction is not required, the pressure-reducing cap 132 is closed, restoring the cover to a sealed state.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
