PCR tube

Abstract

The invention provides a PCR tube. The structure of the PCR tube is as follows, a concave flat mirror is arranged on the top of the tube cover, the top surface of the concave flat cover is lower than that of the tube cover, and an outward protruded circular arc step is arranged on the circle outward surface of the bottom of the tube cover, wherein the vertical section of the circular arc step is segment-shaped; a groove is formed below the tube orifice of the tube body and matched with the circular arc step, wherein the matching type is an interference fit; the vertical section of the tube orifice is of an inverted isosceles trapezoid shape, the upper half part of the tube body is a cylindrical tube body and the lower half part of the tube body is a cone-shaped tube body, wherein the cone-shaped tube body is surrounded by a cone-shaped tube wall, the bottom of the cone-shaped tube body is that of the tube body, the lower end surface of the tube body is the bottom surface of the tube body, and the bottom surface of the tube body is a flat surface. The PCR tube has the advantages that the structure is simple and reasonable, the usage is convenient, the evaporation rate is lowered, the accuracy of the experiment data and the experiment cycle period are improved, the cracking probability of the cone-shaped wall and the cone-shaped bottom is lowered, and the pollution of the PCR device is avoided; the flat mirror is arranged on the top surface of the tube cover and is not easy to be worn and scuffed; the bottom of the tube body is designed to be a flat surface so that the PCR tube can be put upright on a table conveniently.

Description

technical field [0001] The invention relates to a PCR tube. Background technique [0002] PCR, or polymerase chain reaction, is a molecular biology technique used to amplify a specific DNA fragment. It can be regarded as a special DNA replication outside the body. The biggest feature of PCR is that it can greatly increase a small amount of DNA. . In the experiment, a PCR machine is generally used to denature the DNA by raising the temperature, and the single strand is copied into a double strand under the action of the polymerase, thereby achieving the purpose of gene replication. Among them, the PCR tube is an important experimental equipment for PCR. [0003] The sealing structure of the cap of the PCR tube in the prior art tends to cause the evaporation rate to be too high in the case of one experimental cycle, so that the extracted experimental data is inaccurate, thereby affecting the medical diagnosis result. In the experimental cycle, the main heating radiation are...
