Experimental cell centrifugal extractor

Abstract

The invention discloses an experimental cell centrifugal extractor. A rotary drum is vertically arranged in a machine body; a plurality of test tube accommodating cavities on the same circumference are formed in the rotary drum; a mounting plate is horizontally arranged above the rotary drum and is coaxial with rotary drum; a plurality of test tube sealing elements are arranged on the outer circumference of the mounting plate; a storage tube of the extractor is mounted on each test tube sealing element; the extraction end of the storage tube communicates with a test tube; one end of a plunger extends into the storage tube from the upper end of the storage tube, while the other end of the plunger is fixed with the mounting plate; and a driving mechanism is connected with the storage tube and used for driving the storage tube to move towards the plunger. According to the optimally designed experimental cell centrifugal extractor, the structure design is reasonable, on one hand, the test tube sealing elements on the mounting plate seal the open ends of test tubes to ensure that the test tubes cannot swing during centrifugation, on the other hand, the storage tubes extend into the test tubes after centrifugation to achieve in-situ extraction and separation, so that re-mixing, caused by taking out of the test tubes, of layered materials is avoided, and the separation effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of biological cell experiments, in particular to a cell centrifugal extraction machine for experiments. Background technique [0002] The centrifuge is a basic separation instrument in the biological laboratory. It is often used to separate the solid phase and the liquid phase in the colloidal solution. In daily experiments, in order to ensure uniform force in the circumferential direction during centrifugation, it is necessary to manually put in and take out the test tubes one by one, which greatly affects centrifugal efficiency. At the same time, the liquids taken out need to be separated one by one, which affects the work efficiency on the one hand, and on the other hand, after the separated liquid is placed for a period of time, it will melt again and affect the centrifugation effect. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the...

[0002] The centrifuge is a basic separation instrument in the biological laboratory. It is often used to separate the solid phase and the liquid phase in the colloidal solution. In daily experiments, in order to ensure uniform force in the circumferential direction during centrifugation, it is necessary to manually put in and take out the test tubes one by one, which greatly affects Centrifugal efficiency

At the same time, the liquids taken out need to be separated one by one. On the one hand, it affects the work efficiency. On the other hand, after the separated liquid is left for a period of time, it will re-melt and affect the centrifugal effect.
