[0002] The tissue stem cell separation centrifuge is a device used to separate and extract stem cells from tissues. Stem cells are a type of cell with self-renewal and multipotent differentiation capabilities, and have broad application prospects, such as regenerative medicine, tissue engineering, and drug screening.

[0003] Before centrifuging the cells, it is necessary to collect and process the sample containing the target tissue to obtain a cell suspension, add the separation medium and stir evenly to obtain the sample, and put the sample into a test tube for centrifugation. Since the stirring process introduces air into the liquid, air bubbles are generated in the sample, and the air bubbles will mix with the cell suspension. Since the cell mass is very low, the air bubbles will support the cells and prevent them from settling, resulting in uneven cell sedimentation or incomplete separation. Therefore, the present application proposes a tissue stem cell separation centrifuge. Summary of the invention
