Centrifuge - Wikipedia

Centrifuge - Wikipedia

A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction.

Centrifugation - Wikipedia

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

May 09, 2008 Centrifugation for laboratory tests is not as critical as for blood components, but protocols should state centrifuge speed in the appropriate g, and if this cannot be done, then ‘centrifuge’ or ‘gentle centrifugation’ as the case may be, could be used. Standard operating procedures should be in place and should always be followed.
