What is Centrifugation?

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

In this case, mixture is rotated / spun (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 milk and cream
  • 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
