Definition of Centrifugation

Centrifugation is a technique that helps in the separation of molecules from a solution. The particles which are to be separated are suspended in a solution and this solution is kept in a centrifuge tube. This tube is then placed in the rotor of the centrifuge machine and is spun at a defined speed.


This separation can be done by the process of sedimentation too but that takes a great amount of time. Centrifugation consumes much less time and separates the particles more efficiently. The factors that influence the process of centrifugation include the densities of the sample as well as the solution, the temperature, viscosity, and the speed of rotation.
