2.1.4 Loading and overloading of rotors
All approved rotors are listed with their maximum speed and maximum filling weight in „table 2:
permissible net weight“ (see APPENDIX P. VI).
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 rotor), must not be exceeded. The liquids the
rotors are loaded with, should have an max. 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:
Reduced speed n
red
= x max. speed (n
max
) of the rotor
Example:
n
red
= x 4.000 = 3.360 rpm
If In case of any questions, please contact the manufacturer!
2.1.5 Removing the rotor
Untighten the rotor fixing nut complete (2. screw over the stiff point) and lift the rotor vertical out of the
centrifuge. (See figure 10 and 11)
