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 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 n
