Centrifugation

What is Centrifugation?

It is the process of separating the particles using centrifugal force.

In this case, mixture is rotated  (moved to go round) resulting in denser particles moving down while lighter particles move up.

It is done by using a centrifuging machine or manually by using milk churner

Uses of Centrifugation

• It is used in dairies to separate cream from milk
• It is used in labs for blood and urine tests
• It is used in washing machines to squeeze out water from clothes

Advantage of centrifugation over other methods

Sometimes the solid particles in a liquid are very small and pass through the filter paper .

For such mixtures, the filtration technique can not be used for separation.

Such mixtures are separated by centrifugation
