The centrifuge uses centrifugal force (the force generated when an object rotates around a single point), for separating solids suspended in a liquid by sedimentation or liquids of diverse density. The rotational movements allow forces much greater than gravity to be generated in controlled periods of time. Centrifuges are generally used in the laboratory in processes such as the separation of solid components from biological liquids through sedimentation and for conducting multiple tests and treatments.
