radius. The speed is expressed in revolutions per minute (rpm)‚ and the centrifugal force generated is expressed in terms of relative centrifugal force (RCF) or gravities (g). The speed of the centrifuge is related to the RCF by the following equation: RCF 1.118 105 r (rpm)2 where 1.118 105 is a constant‚ determined from the angular velocity‚ and r is the radius in centimeters‚ measured from the center of the centrifuge axis to the bottom of the test-tube shield. The RCF value
