Filtering separating device for bioengineering

Abstract

The invention discloses a filtering separating device for bioengineering. The device structurally comprises a separating bin, a connecting ring, an inactivation device, a fixed base and supporting feet. The separation bin is mounted on the fixed base, the two supporting feet are mounted on the bottom of the fixed base, and are arranged to be of a symmetric structure, the supporting feet are mechanically welded with the fixed base, and the inactivation device is mounted in the separating bin. The device has the beneficial effects that through outer mechanical force, two movable rods are controlled to oppositely and inconsistently move, opposite and inconsistent motion control between a sub grinding head and a main grinding head can be achieved, biological sample residue remaining on the inner wall of an output pipe is ground, biological sample residue between the sub grinding head and the main grinding head gets close to along with the sub grinding head and the main grinding head, a grinding needle is embedded with an embedded groove in the end, away from a fixed groove, of a fixed rod, smashing of the biological sample residue is more thorough, and the reaction between remaining biological samples and next separated biological samples can be avoided.

Description

technical field [0001] The invention relates to the field of biological filtration, in particular to a filtration and separation device for bioengineering. Background technique [0002] In the process of biological experimental detection, when the organisms are separated by layers with upper and lower structures, to obtain the lower layer of biological samples, it is necessary to probe the test tube from the upper layer of biological samples and suck them out. Although the middle section is intercepted for experimental detection, the lower layer There will still be a small amount of upper biological samples in the biological samples, which will affect the accuracy of the experimental results. Therefore, the separation and filtration of biological samples needs to be further explored.

[0002] In the process of biological experimental detection, when the organisms are separated by layers with upper and lower structures, to obtain the lower layer of biological samples, it is necessary to probe the test tube from the upper layer of biological samples and suck them out. Although the middle section is intercepted for experimental detection, the lower layer There will still be a small amount of upper biological samples in the biological samples, which will affect the accuracy of the experimental results. Therefore, the separation and filtration of biological samples needs to be further explored. The current filtration and separation equipment for bioengineering has the following defects:

[0003] The existing bioengineering filtration and separation equipment solves the problem that the test tube is inserted from the upper biological sample and the lower biological sample is taken out, which will cause the sample to contain the upper biological sample by extracting the upper biological sample from the top and the lower biological sample from the bottom. The problem with the sample is that after the extraction of the biological sample is completed, the method of clearing the biological sample from the extraction port of the lower layer will leave some biological samples remaining, resulting in impure extraction of the next biological sample
