Separation by Centrifugation - GeeksforGeeks

2021-8-3 · Centrifugation is a mechanical technique for separation which involves the usage of the centrifugal force to separate particles contained in a solution.The particles are segregated depending on their size, shape, density, and rotor speed. The suspended particles in a mixture are rotated at a high speed in a machine, called the centrifuge in order to segregate the particles from the liquid.
