[0002] The cell detection centrifuge is a device used to separate and detect cells. It uses the principle of centrifugation to settle the cells in the mixed cell suspension to the bottom of the centrifuge tube or centrifuge disk to achieve cell separation and concentration. A common centrifuge uses centrifugal force to settle the cells to the bottom of the centrifuge tube, then removes the supernatant, leaving the cell pellet for subsequent testing. The centrifugal separation column adds the cell suspension to the column, separates the cells into different layers by centrifugal force, and then collects them layer by layer for testing. The cell detection centrifuge is widely used and can be used for cell screening, cell counting, cell analysis, etc.

[0003] However, when the existing centrifugal device rotates the internal test tube, the fixing structure of the device itself is not perfect, which can easily cause the test tube to be thrown out, thereby causing the test tube to break, affecting the working efficiency of the detection.
