Centrifuge test commonly used methods include differential centrifugation, such as density gradient centrifugation, density gradient centrifugation speed zone, balance, density gradient centrifugation, zone centrifugation, continuous flow centrifugation, centrifugal washing and other methods.

Used differential centrifugation to separate the various subcellular and crude nucleic acid, protein. Density gradient centrifugation, density gradient centrifugation speed zone, balance, density gradient centrifugation as biological macromolecules, organic molecules, subcellular, viruses, proteins, nucleic acids and other biological research technology a powerful tool indispensable. Zone is to use centrifugal rotor zone centrifugation, and centrifugation is a general laboratory separate suspended solids from the solution, the most widely used separation method. Centrifuge is mainly used for washing the whole cell centrifuge. Continuous flow centrifugation in the production of industrial scale fermentation and cell culture medium for the separation, can also be used to separate cells in different growth periods.
