3.1.2 Loading angle rotors
Rotors must be loaded symmetrically and with equal weight (see figure below). The adapter may only be loaded with
the appropriate vessels. The weight differences between the filled vessels should be kept as low as possible.
Therefore, we recommend weighing them with a balance. This reduces the wear of the drive and the acoustic
operating noise.
On each rotor, the maximum load per hole is stated.

3.1.3 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).
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 a maximum 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:

If in case of any questions, please contact the manufacturer!
3.1.4 Removing the rotor
Untighten the rotor fixing nut completely (screw over the stiff point) and lift the rotor vertical out of the centrifuge. (see
figure 8).
3.1.5 Power switch and fuse
The power switch is located on the back side or in the front of the centrifuge (see figure 11).
ATTENTION: After turning on the power switch, open the centrifuge lid first, before starting the centrifuge
