AI Technical Summary

Technical Problem

Traditional PCR amplification tubes have a sealing cap that is easy to remove during heating, which poses a risk of reaction solution contamination and is inconvenient to operate. Existing sealing devices with fixed structures are prone to contamination when the tube opening is open when adding reaction solution.

Method used

A sealing device comprising a cover plate, a slide bar, a compression spring, and a limiting structure is designed. The cover plate moves radially, and the slide bar and compression spring work together to achieve rapid sealing and opening. The limiting structure ensures that the sealing sleeve is flush with the cover plate, preventing air pressure changes from affecting the sealing effect.

Benefits of technology

It achieves effective sealing of the reaction solution during heating, avoids contamination, is easy to operate, and ensures the accuracy of experimental results.

Abstract

The utility model relates to a PCR amplification tube, including the sealed structure of tub body and setting at the top of tub body, the tub body upper portion symmetry is provided with two mounting blocks along its radial, the sealed structure includes the cover plate that can move along the radial of tub body, and the both sides of cover plate are equipped with connecting plate respectively, and two connecting plates are equipped with the slide bar respectively for with two mounting blocks sliding fit, and first compression spring is connected between connecting plate and mounting block, push slide bar, and cover plate exposes the pipe orifice, and loosen slide bar, and cover plate is driven under the first compression spring and covers the pipe orifice, and the middle part of cover plate is equipped with the sealing sleeve that can move up and down along its height direction, and sealing sleeve is used for sealing the pipe orifice, and the limiting structure for limiting sealing sleeve after moving is equipped on sealing sleeve, and under the initial state, sealing sleeve downside is flush with the downside of cover plate. This PCR amplification tube can seal the pipe orifice after adding reaction liquid to the tub body quickly, not only sealed effect is good, avoids the pollution of reaction liquid, and also is convenient to operate.
