Solution
Different separation techniques are present depending on the property of the substances to be separated.
Centrifugation is a separation technqiue which uses the principle "density difference of the components".
When the mixture of components having different density, rotated (or spun) using a centrifugal machine the denser particles are forced to move to the bottom and separated.
Milk is a colloid, where the fat globules are dispersed in the medium (water).
We can separate cream from milk using the centrifugation technique.
The particles which are small in size (i.e which can not separate using ordinary filter paper) separated using this process.
A simple centrifuge (in the laboratory) has a vertical shaft carrying four or more test tube holders where the mixture is put for rotation.
The centrifugal force acts on the particles and forced particles to settle down at the bottom.
Below mentioned picture depicts a simple centrifuge.
Therefore, a centrifuge is used to carry out the centrifugation process.
