gravity. Particles with different density and masses are settled at different rates in a tube which are response to gravity. Centrifuge is an instrument which can spin carrier vessels at high rotation speed and very high centrifugal force to allow centrifugation. The centrifugal force generated is proportional to the rotation rate of the rotor and the distance between the rotor centre and the centrifuge tube. There are three general classes of centrifuges: low speed‚ about 5000 rpm‚ high speed machine
