Sampling device for biotechnological separation

Abstract

The invention discloses a sampling device for biotechnology separation. The device comprises a separation box, a sampling cylinder and a dosing box; the separation box is positioned between the sampling cylinder and the dosing box; a rotating motor is arranged at the center of the top of the separation box; the output end of a rotary motor is connected with a stirring shaft extending into the separation box; the stirring shaft is provided with a plurality of rotary crushing cutters; fixed crushing cutters staggered relative to the rotary crushing cutters in a vertical direction are arranged onthe inner wall of the separation box; and a sample inlet communicated with the interior of the separation box is formed in the top of the separation box. According to the sampling device, the rotarycrushing cutters and the fixed crushing cutters which are arranged in a staggered manner are arranged in the separation box to crush a sample; a solution is conveyed into a sample layer through the dosing box, so that the sample can be crushed and stripped off sequentially, and therefore, separation efficiency can be ensured, and sampling accuracy is improved; and the sampling cylinder is adopted,and therefore, a sampling process is convenient, the possibility of misoperation is reduced, and a condition that the sample is polluted is avoided.

Description

technical field [0001] The invention relates to biotechnology, in particular to a sampling device for biotechnology separation. Background technique [0002] Cell separation techniques include centrifugation, flow cytometry, and cell electrophoresis. Centrifugation is the basic means for studying such as nuclei, mitochondria, Golgi apparatus, lysosomes and microbodies, as well as various macromolecules. Flow cytometry is a technique for rapid quantitative analysis and sorting of single cells. Cell electrophoresis means that at a certain pH value, the cell surface has a net positive or negative charge, and can swim under the action of an external electric field. [0003] The current separation and sampling devices of biotechnology are complex in structure and high in price, and are only used in a small amount in clinical practice, and the operation is complicated during the separation process, and it is easy to contaminate cell samples and affect the accuracy of sampling. ...
