Rcf Value Explained - VWR avantor Micro Star 21 Instruction Manual

RCF Value Explained

The relative centrifugal force (RCF) is given as a multiple of the force of gravity (g). It is
a unitless numerical value which is used to compare the separation or sedimentation
capacity of various centrifuges, since it is independent of the type of device. Only the
centrifuging radius and the speed are used for calculation:
r = centrifuging radius in cm
n = rotational speed in rpm
The maximum RCF value is related to the maximum radius of the tube opening.
Remember that this value is reduced depending on the tubes, buckets and adapters
used.
This can be accounted for in the calculation above if required.
Use of Tubes and Consumables
Make sure that the tubes and bottles used in the centrifuge are:
rated to or above the selected RCF to be spun at,
ƒ
never used not below their minimum fill volume and never above their maximum fill
ƒ
volume,
not used above their design life (age or number of runs),
ƒ
undamaged,
ƒ
fitting well into the cavities.
