PCR technology is one of the most important and commonly used techniques in biological research today, and almost all molecular biology laboratories need to perform PCR reaction operations. During the PCR reaction operation, it is difficult to ensure that the lids of PCR tubes are fully closed, and it is not easy for the operator to detect which PCR tubes are not tightly closed. In that case, because the PCR reaction often needs to be heated to 94 degrees Celsius Or higher temperature, if the lid of the PCR tube is not tightly closed, the liquid in the PCR tube will escape due to evaporation during the PCR reaction, thereby changing the PCR reaction system, resulting in the failure of the PCR reaction, and even the entire liquid is evaporated to dryness.

Moreover, in the teaching process of biological experiments in universities, due to the large number of students or the large number of samples for other scientific research tasks, it is often necessary to carry out a large number of PCR reactions, the number of which is dozens or often hundreds of thousands. Teachers do not have the time and energy to check and verify whether the lid of each PCR tube is tightly closed one by one. Therefore, there must be a simple and practical tool to solve this problem.
The flat-ended PCR tube lid pressing device for laboratory is characterized in that it is composed of a handle, a rolling wheel, a squeeze ring and a locking screw pin of the squeeze ring; wherein, one end of the handle has a U-shaped groove, and the rolling wheel The two ends of the shaft are fixed to the two arms of the U-shaped groove, so that the rolling wheel can rotate flexibly in the U-shaped groove; It is composed of arc blocks, the extrusion ring locking bolt is used to lock each arc block of the extrusion ring to make it relatively fixed; the middle part of the handle is a cylindrical body, and the cylindrical body is provided with several arcs at intervals up and down. The inner groove is easy to hold with fingers; the rolling wheel is a cylindrical structure, the height of the cylinder is less than the diameter of the PCR tube cover, and the arc surface of the cylinder has a number of annular ridges parallel to the cylinder edge, and the ridge is Convex or concave.
