Centrifugation - Centrifuge Definition, Centrifuge Machine ...

Centrifugation definition. Centrifugation is the process that uses centrifugal force for the separation of two liquids in a mixture. In this process, denser component of the mixture migrates away from the axis and lighter component migrates towards the axis. The process of centrifugation is carried out in a centrifuge, as shown in Fig 7.

Centrifugal Purifiers Basic Principle and Working on Ships

In the above case it is gravity that is responsible for the settling out and this takes quite a while. If the gravitational force is increased, by using centrifugal force, the separation effect is much greater. This is shown in figure below by imagining settling tank on its side and rotated, which is the basic principle of centrifugal purifiers.
