RNA grinding and extracting system

Abstract

The invention discloses an RNA grinding and extracting system. The RNA grinding and extracting system comprises a box body and a liquid nitrogen tank, wherein the box body is of a cuboid structure, four supporting legs are fixed on the bottom of the box body, a liquid discharge pipe communicates to the lower portion of the box body, a valve A is installed on the liquid discharge pipe, a liquid storage box is arranged below the liquid discharge pipe, the liquid discharge pipe communicates with the liquid storage box, and the front surface of the box body is movably connected with a box door through a hinge. The RNA grinding and extracting system is reasonable in structural design and convenient to use. RNA is ground and extracted by mechanical milling. In the way, an operation process of manual grinding is omitted, and operation is simplified. Meanwhile, when liquid nitrogen is introduced, limbs can be prevented from being directly in contact with the liquid nitrogen, cold injury of hands by the liquid nitrogen is avoided, and the safety is greatly improved. A rotary grinding mode is adopted for mechanical grinding, and a grinding piece is pushed by an air cylinder, thus, a grindinghead of the grinding piece is abutted to a grinding groove, the grinding piece can be fully in contact with the grinding groove when a motor drives the grinding piece to rotate, and the grinding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of RNA grinding, in particular to an RNA grinding and extraction system. Background technique [0002] Liquid nitrogen grinding is widely used in molecular biology experiments, especially the separation of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). The temperature of liquid nitrogen is -196°C. It can not only make various tissue components not easy to be destroyed or degraded, but also harden the tissue, making it more brittle and easy to grind. [0003] The existing RNA grinding device needs to manually grind and extract RNA. For this reason, the arms need to be kept warm, and antifreeze gloves need to be worn to avoid freezing the limbs with liquid nitrogen. The overall operation is complicated and difficult to use, time-consuming and laborious. The efficiency of RNA grinding and extraction is low. At the same time, if the movement is too large, the sample will be splashed, and it is easy to ...
