Centrifuge

A centrifuge is a device used for separating particles from a solution according to density. The centrifuge spins the samples around an axis to produce centrifugal forces. The radial force generated by the spinning rotor is expressed relative to the earth's gravitational force. It is known as the relative centrifugal force (RCF) or the g force.

Rotors from different manufacturers can have different standards; therefore, it is better to use relative centrifugal forces (RCF) to measure the centrifugation force instead of revolutions per minute (rpm).

It is important to ensure that loads are evenly balanced before running the centrifuge.
