2 OPERATION
2.1.3 Overloading of rotors
The maximum load permitted for a rotor, which is determined by the manufacturer, as well as the
maximum speed allowed for this rotor (see label on the rotor), must not be exceeded.
The liquids the rotors are loaded with, should have an average homogeneous density of 1.2 g/ml or less when
the rotor is running at maximum speed.
In order to spin liquids with a higher density, the speed has to be reduced according to the following
formula:
1.2
Reduced speed nred = x max. speed (nmax) of the rotor
higher density
Example:
1.2
nred = x 4.000 = 3.360 rpm

flashing word "rcf" (7) appears.
You can set the desired values with the adjusting knob (9). In the display (17) the regulated value is
shown permanently, before, during and after the run.
As long as no rotor is inserted, the speed is adjustable between 200 rpm and the maximum revolution of the
centrifuge.
If there is a rotor in the centrifuge the speed can only be pre-selected until the maximum permissible
revolution of that rotor.
It is the same with the pre-selection of the RCF-value. The setting range is between 20 xg and the
maximum permissible centrifugal force of the rotor. The maximum speed of the VELOCITY 30R is 30000
