As we all know, a centrifuge is a machine that uses centrifugal force to separate components from liquid and solid particles or a mixture of liquid and liquid. Centrifuges are mainly used to separate solid particles from liquids in suspension, or to separate two immiscible liquids with different densities in emulsions; it can also be used to remove liquids in wet solids, such as with a washing machine Drying wet clothes; special superspeed tube separators can also separate gas mixtures of different densities; using the characteristics of different densities or particle sizes of solid particles in liquid sedimentation speed, some sedimentation centrifuges can also separate solid particles according to density or particle size classification. For the centrifugal devices currently used in the laboratory, they usually have a centrifuge shell, an inner centrifuge box, etc. The inner centrifuge box usually uses components such as motors to drive centrifugal rotation, but the inner centrifuge box lacks corresponding support. In the process of centrifugation, if the speed is slightly faster, the stability will be poor; in addition, it is inconvenient to extract the upper liquid after centrifugation, and the centrifugation method is relatively simple.
