Relative centrifugal force RCF and centrifuging radius RAD
7.1.6
Centrifugation of substances or mixtures of substances with a density higher than
1.2 kg/dm
26 / 39
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.
The relative centrifugal force (RCF) is dependent on the centrifuging radius
(RAD). After entering the RCF, check that the correct centrifuging radius is
set.

The density of the substances or mixtures of substances must not exceed
1.2 kg/dm³ during centrifugation at maximum speed. The speed must be
reduced for substances or substance mixtures with a higher density. The
permissible speed can be calculated using the following formula:
For example: Maximum speed 4000 RPM, density 1.6 kg/dm³
If, in exceptional cases, the maximum load indicated on the bucket is
exceeded, the speed must also be reduced. The permissible speed can
be calculated using the following formula:
For example: Maximum speed 4000 RPM, maximum load 300 g, actual
load 350 g
Please contact the manufacturer if you are not sure.
