What is the centrifugation process?

Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, the viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. The tube is then placed in a rotor and spun at a given speed.

Example: If we take some milk in a centrifugation machine and spin it rapidly, the cream separates from the milk because the cream is less dense than milk.
