Histocyte nucleic acid extraction cryogrinding box

Abstract

The invention discloses a histocyte nucleic acid extraction cryogrinding box, which comprises a shell, a first side plate is arranged on one side of the shell, a second side plate is arranged on the other side of the shell, a sliding rail is arranged at one sides of the first side plate and the second side plate, a sliding strip is arranged in the sliding rail, the first side plate is connected with a driving plate through the sliding strip, fixing frames are arranged at two ends of the first side plate, fixing columns are arranged in the fixing frames, a mounting frame is arranged on the fixing columns, racks are arranged on the top end and the bottom end of the mounting frame, incomplete gears are meshed on the racks, the second side plate is connected with a driven plate through the sliding strip, spring grooves are formed in two sides of the driving plate and the driven plate, springs are arranged in the spring grooves, the driving plate and the driven plate are connected with a scraper device through the springs, and the scraper device is composed of a scraper blade, a mounting plate and a connecting column. The histocyte nucleic acid extraction cryogrinding box provided by the invention is better in grinding effect and is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of biotechnology, in particular to a low-temperature grinding box for extracting nucleic acid from tissue cells. Background technique [0002] The extraction of nucleic acid from animal and plant tissues is an important step in molecular biology experiments. The quality of nucleic acid extracted in this step will directly affect the results of the experiment. This process requires the use of a grinding process. [0003] During the use of the existing grinding box, the ground material will stick to the grinding disc, and it will be cleaned after grinding, but the grinding effect will be affected during the grinding process, which will affect the use. Contents of the invention [0004] The object of the present invention is to provide a low-temperature grinding box for tissue cell nucleic acid extraction to solve the problem that in the prior art, the ground material will stick to the grinding disc, and it w...
