Loading And Overloading Of Rotors; Removing The Rotor - Hermle Z 326 Operating Manual

OPERATION

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 is determined by the manufacturer, as well as the maximum
speed allowed for this rotor (see label on rotor), must not be exceeded. The liquid the rotors are
loaded with, should have a 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
Example:
In case of any questions, please contact the manufacturer!

2.1.5 Removing the Rotor

Completely, untighten the rotor fixing nut (2. screw over the stiff point) and lift the rotor vertically out of
the centrifuge, (see Figures 9 and 10).
