Abstract

The invention provides a molecular biology experiment sample grinder, and relates to the technical field of biological sample treatment, the molecular biology experiment sample grinder comprises a base, the base is provided with a placing rack and a mounting rod, the placing rack is provided with a plurality of second pipe bodies, the top end of the mounting rod is provided with a driving member, the output end of the driving member is provided with a lifting assembly, and the lifting assembly is provided with a plurality of second pipe bodies. And a first pipe body is arranged in the second pipe body. According to the device, the ball is provided with the rotating assembly used for driving the ball to rotate, the lifting assembly drives the first pipe body to move up and down in a reciprocating mode, samples in the second pipe body are continuously extruded through the ball, the effect of grinding the samples is achieved, and meanwhile along with the up-down reciprocating motion of the first pipe body, the ball is driven to rotate in the upward moving process of the first pipe body; and therefore, the sample adhered to the surface of the ball is scraped off through the scraping between the ball and the lower end of the first pipe body, so that the sample is fully ground, and the grinding uniformity is improved.

Description

technical field [0001] The invention belongs to the technical field of biological sample processing, and more particularly relates to a molecular biology experimental sample grinder. Background technique [0002] In the field of molecular biology research and experiments, the separation and extraction of specific biological samples such as nucleic acids and proteins from biological samples is a very common operation and the basis for all subsequent research and experiments. Commonly used biological samples include animal tissue, plant tissue and microorganisms. [0003] Currently, a variety of methods can be used to achieve the extraction of specific biological samples. The operator selects different methods according to the difference of the original biological samples, and combines them according to certain steps to realize the extraction of specific biological samples. Among them, a commonly used combination of operations is: first, grind the biological sample into powd...
