Description

Technical Field

[0001] This invention relates to the field of biochemical laboratory tools technology, and more specifically to a device for opening PCR tubes. Background Technology

[0002] Current PCR tube openers typically insert from the side and separate the cap, which can easily cause small amounts of liquid inside the tube to splash. They cannot open multiple tubes arranged together sequentially; they can only open the outermost tubes. Furthermore, due to their side-opening structure, they generally do not have the function of capping or opening centrifuge tubes. Summary of the Invention

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide a device for opening PCR tubes, realizing the functions of opening and sealing PCR multi-tube tubes, and also realizing the function of opening small-capacity centrifuge tubes. It solves the problem that it is inconvenient to open the tubes when wearing gloves, solves the problem of solution leakage caused by manual opening, and improves work efficiency.

[0004] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0005] A device for opening PCR tubes includes a cap opener body. The lower end of the cap opener body is provided with several cap opening plugs for inserting into the tube cap gap of the PCR tube and prying open the cap. The side end of the cap opener body is provided with a centrifuge tube cap opening groove for inserting the centrifuge tube cap into the centrifuge tube cap opening groove and prying open the cap.

[0006] Furthermore, the upper end of the cap opener body is provided with a PCR tube capping groove for pressing down the cap of the PCR tube and fastening the cap to the PCR tube.

[0007] Furthermore, the main body of the lid opener is provided with a hanging hole for hanging it on the workbench for easy access.

[0008] Furthermore, the shape of the cap-opening plug is the same as the shape of the connection point of the PCR tube.

[0009] Furthermore, the plurality of capping plugs consist of a single plug and a multi-connector plug. The single plug is located at the lower edge of the capping device body and is used to open the caps of individual PCR tubes. The multi-connector plug is located at the lower middle of the capping device body and is used to open the caps of multiple PCR tubes at the same time.

[0010] Furthermore, the PCR tube capping groove is an arc-shaped groove that is high in the middle and low on both sides, so as to facilitate capping by rotating and pressing down.

[0011] The beneficial effects of this invention are:

[0012] 1. Solve the problem of liquid splashing inside the tube when the cap is opened manually.

[0013] 2. Solve the problem that it is inconvenient to pinch the cap to open it manually when wearing gloves.

[0014] 3. Solved the problem of needing to press down on each cap when manually attaching the PCR tube caps.

[0015] 4. Solved the problem that the caps of PCR tubes could not be opened row by row without moving the tubes when they were placed on a 96-well plate rack. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown, a device for opening PCR tubes includes a cap opener body 5. The lower end of the cap opener body 5 is provided with several cap opening plugs 1, which are used to insert into the tube cap gap of the PCR tube and then gently pry it to the left or right to achieve the separation of the tube and the cap. The side end of the cap opener body 5 is provided with a centrifuge tube cap opening groove 3, which is used to pry open the centrifuge tube cap by inserting it into the centrifuge tube cap opening groove 3.

[0023] The upper end of the cap opener body 5 is provided with a PCR tube capping groove 4, which is used to press down the tube cap of the PCR tube and fasten the tube cap to the PCR tube.

[0024] The main body 5 of the lid opener is provided with a hanging hole 2 for hanging it on the workbench for easy access.

[0025] The shape of the cap-opening plug 1 is the same as the shape of the connection of the PCR tube, that is, the cross-sectional shape of the cap-opening plug 1 is the same as the shape of the gap between the tube caps.

[0026] The plurality of capping plugs 1 consist of a single plug and a multi-connector plug. The single plug is located at the lower edge of the capping device body 5 and is used to open the caps of individual PCR tubes. The multi-connector plug is located at the lower middle of the capping device body 5 and is used to open the caps of multiple PCR tubes at the same time. In this embodiment, the multi-connector plug is a 7-connector plug. A single plug can open the caps of 2-3 individual PCR tubes, and a 7-connector plug can open the caps of 8 PCR tubes at the same time.

[0027] The PCR tube capping groove 4 is an arc-shaped groove that is high in the middle and low on both sides, so as to facilitate capping by rotating and pressing down. Since multiple tube caps need to be capped at the same time, they can be rotated and pressed down at once to quickly fasten multiple caps to the test tubes.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
