Expert Answer:

Centrifugation is done by using a machine called centrifuge.

In the method of centrifugation, the mixture of fine suspended particles in a liquid is taken in a test-tube. The test-tube is placed in a centrifuge machine and rotated rapidly for some time. As the mixture rotates round rapidly, centrifugal force acts on the heavier suspended particles in it and forces them down to the bottom of the test-tube. The clear liquid, being lighter, remains on top.
