12 Relative centrifugal force (RCF)
The relative centrifugal force (RCF) is given as a multiple of the acceleration of gravity (g). It is a unit-free value and
serves to compare the separation and sedimentation performance.
These values are calculated using the formula below:

RCF = relative centrifugal force
RPM = rotational speed (revolutions per minute)
r = centrifugal radius in mm = distance from the centre of the turning axis to the bottom of the centrifuge.
For more on the centrifugal radius see the chapter ” Anhang/Appendix,
Rotoren und Zubehör/Rotors and accessories”.
The relative centrifugal force (RCF) stands in relation to the revolutions per minute and the centrifugal
radius.
13 Emergency release
The lid cannot be opened during power failure. An emergency release has to be executed by hand.
For emergency release disconnect the centrifuge from the mains.
Open the lid only during rotor standstill.
Only the plastic release pin attached at the bottom of the centrifuge may be used for emergency release.
The release pin is fixed with a clamp at the bottom of the centrifuge and tied to it with a plastic cord.
1. Switch off the mains switch (switch position "0").
2. Pull out the release pin and uncoil the cord, see drawing.
3. Insert the release pin horizontally into the hole located in the middle of the front panel, see drawing.
4. Push the release pin to the right, then up to a 45° position. Pull the lid upwards at the same time to unlock, see
drawing.
5. Pull the release pin out and recoil the cord around the clamp. Re-fasten the release pin as shown below.
