Relative centrifugal force (RCF)

The quoted permissible RCF values (identical to g values)
refer to filling with water and 20 min centrifugation time
at 20°C. However, the actual stress limit is affected to a
large extent by conditions such as the positioning in the
rotor, chemicals, temperature and running time. There-
fore, the RCF values must only be understood as a
general guide. (DIN 58970).

Equation to calculate RCF:
RCF = 1,118 x r x (n/1000)2

Example:
Rotation radius r = 180 mm
(vertical distance between center of rotation axis and bottom end of centrifuge tube)
Speed n = 6000 min-1 (rotations per minute divided by 1000)

RCF = 1,118 x 180 x (6000/1000)2
       = 7245
