[0002] A cell separator is a precision instrument used in biomedical research. Its main function is to separate cells for subsequent experiments and analysis. It mainly generates centrifugal force through a centrifugal module to separate cells in a centrifuge tube. The liquid and cells in the centrifuge tube will be stratified under the action of centrifugal force, so that different types of cells can be separated. This process is also called cell sedimentation or cell separation, and its use scenarios are very wide. It can be used in many fields such as hematology, oncology, immunology, and biochemistry. For example, in hematology, a cell separator can be used to separate white blood cells, red blood cells, platelets, etc.; in oncology, it can be used to separate tumor cells and normal cells to study the growth and spread of tumors. Centrifuge tubes are tubular sample containers that can be equipped with sealing covers or glands. Cell separation devices that prevent centrifuge tubes (centrifuge tubes are usually used in centrifuge operations to separate particles or cells in liquids, etc.) from detaching can adopt a variety of designs and mechanisms to ensure that the centrifuge tubes can be firmly fixed on the centrifuge turntable during high-speed centrifugation operations. Therefore, a cell separation device that prevents centrifuge tubes from detaching is needed, which is convenient for preventing centrifuge tubes from detaching and for quickly disassembling and assembling the placement rack.
