Description

Technical Field

[0001] The utility model belongs to the technical field of cell filters, in particular to a cell filter. Background Art

[0002] During primary cell culture, the culture product obtained after cells, tissues, and organs are directly removed from the body and before being subcultured generally contains not only cells but also fragments of the original tissues, organs, cell clumps, and culture medium that have not yet been fully dispersed. Therefore, the culture mixture must be initially filtered and separated before the product is collected. Filtration requires centrifuging the culture medium, but this is inconvenient during liquid transfer and can easily cause contamination. Furthermore, the filter screen is prone to clogging and inconvenient to clean after prolonged use.

[0003] A cell filter is disclosed, with the publication number CN211771269U. The beneficial effects are as follows: the cell filter has a lower hopper and a material guide tube inside the bottom cylinder, which cooperate with the bottom plate and fixed block at the bottom of the cylinder to facilitate the fixation of the centrifuge tube and convenient sampling. A cleaning brush is provided inside the inner cylinder. When the sliding cylinder slides, the cleaning brush is driven close to the filter screen to clean the filter screen and prevent it from being blocked.

[0004] The cell filter is equipped with a lower hopper and a guide tube inside the bottom cylinder, which cooperates with the bottom plate and fixed block at the bottom of the cylinder to facilitate the fixation of the centrifuge tube and convenient sampling. However, in actual use, the sample liquid measured for the internal experimental sampling is too small. When a large amount of sample liquid is needed for experiment, the device has certain usage defects. Based on this, a cell filter is proposed to solve the above problems. Utility Model Content
