Cell research centrifugal equipment for fixing test tube through negative pressure

Abstract

The invention relates to the technical field of biological cells, and discloses cell research centrifugal equipment for fixing a test tube through negative pressure. The cell research centrifugal equipment comprises a motor, the top of the motor is rotatably connected with a rotating shaft penetrating through a fixed table, the top of the rotating shaft is fixedly connected with a storage plate, storage cylinders arranged at equal intervals are inserted into the tops of the storage plate, storage grooves are formed in the tops of the storage cylinders, air cavities are formed in the lower portions of the interiors of the storage cylinders, threaded rods are rotatably connected to the inner top walls of the air cavities, pinions are fixedly connected to the bottoms of the threaded rods, andthe threaded rods is sleeved with pistons and ratchet wheels. When the pistons reach the bottom wall of the air cavity, the pistons stop moving downwards, the threaded rods drive the storage cylinders to rotate on the storage plate under the action of the pinions, so that the effect that the centrifugal test tube rotates while revolving around the center of the storage plate is achieved, the movement of the centrifugal test tube is more variable and complex, and the centrifugal effect of biological cells is better.

Description

technical field [0001] The invention relates to the technical field of biological cells, in particular to a centrifugal device for cell research that fixes test tubes through negative pressure. Background technique [0002] Biological cells are a type of cells with unlimited self-renewal ability, generally able to produce at least one type of highly differentiated progeny cells, biological cells have extremely broad applications in the fields of cell repair, developmental biology, and pharmacology in life sciences Foreground, so scientists often need to use centrifuge equipment to separate and study biological cells. [0003] When the centrifuge equipment used for general biological cell research is centrifuged, the centrifuge test tube only revolves around the center of the plate, and the acceleration is all centripetal acceleration. There is no acceleration in the tangential direction, so it cannot achieve a good centrifugation effect. The fixing effect is not good, so th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a centrifuge device for cell research that fixes the test tube by negative pressure, which has the advantages of good centrifugation effect and firm fixation of the test tube, and solves the problem of centrifugation of the centrifuge test tube when the general centrifuge device is centrifuged. There is no acceleration in the tangential direction, so the centrifugation effect cannot be achieved, and the centrifuge test tube is easy to collide with the side wall of the storage tank when rotating, and even cause the test tube to be damaged, resulting in centrifugation failure.
