Centrifuge: Principle, Types and Application

A centrifuge is a powerful device utilized for separating and purifying mixtures by employing centrifugal force. It effectively separates particles based on their size, shape, density, viscosity, and rotor speed. The process involves the sinking of particles with higher density to the bottom while the lighter ones float to the top.
