A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate the two liquids in the emulsion with different densities and incompatible with each other. It can also be used to remove the liquid in the wet solid. Laboratory centrifuges are essential equipment for scientific research and production in biology, medicine, agronomy, bioengineering, and biopharmaceutical industries.
