Grinding device for molecular biology sample inspection and analysis

Abstract

The invention discloses a powder grinding device for sample inspection and analysis in molecular biology, and relates to the field of sample inspection, the powder grinding device comprises a support and a powder grinding cylinder mounted on the support, a mounting seat is fixed in the powder grinding cylinder, a grinding hopper is embedded in the middle of the mounting seat, a grinding block is embedded in the grinding hopper, and the grinding block is embedded in the mounting seat. A crushing assembly is connected to the top end of the grinding block, a moving plate is arranged above the grinding cylinder, a driving motor is installed in the middle of the upper side of the moving plate, a rotating shaft is connected to the output end of the driving motor, the lower end of the rotating shaft movably penetrates through the moving plate, and the lower end of the rotating shaft extends into the grinding cylinder to be connected with the crushing assembly. According to the molecular biology sample grinding device, a molecular biology sample is cut and smashed through a first cutting blade and a second cutting blade in the smashing assembly, the size of the molecular biology sample is reduced, the smashed sample is ground into powder through a grinding block and a grinding hopper, and the powder grinding effect and the powder grinding efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of sample testing, in particular to a grinding device for molecular biology sample testing and analysis. Background technique [0002] Molecular biology is a science that studies the structure and function of biological macromolecules at the molecular level to clarify the nature of life phenomena. Since the 1950s, molecular biology has been the frontier and growing point of biology, and its main research fields include protein systems, protein-nucleic acid systems and protein-lipid systems. The research content includes various life processes. Such as photosynthesis, molecular mechanism of development, mechanism of neural activity, carcinogenesis, etc. The study of the structure and function of biological macromolecules, especially proteins and nucleic acids, is the foundation of molecular biology. [0003] In the study and research of molecular biology, it is often necessary to grind the samples of molecular biolo...
