Centrifugation Theory. Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. The theoretical basis of this technique is the effect of gravity on particles (including macromolecules) in suspension.Two particles of different masses will settle in a tube at different rates in response to gravity. commonly used technique for cell fractionation, called differential centrifugation, is used to separate particles from a liquid medium or to separate particles of different masses into separate fractions of the supernatant.
