The relative centrifugal force RCF is dependent on the speed and the centri-
fuging radius.
The relative centrifugal force RCF is stated as a multiple of the acceleration
due to gravity (g).
The relative centrifugal force RCF is a dimensionless numerical value and is
used to compare the separation and sedimentation performance.
RCF = Relative Centrifugal Force
RPM = speed
r = centrifuging radius in mm = distance from the centre of the axis of
rotation to the bottom of the centrifuge tube.
