5.5.1
Loading the rotor
CAUTION! Risk of injury due to asymmetric loading of a rotor.
Load rotors symmetrically with identical tubes.
Only load adapters with suitable tubes.
Always use the same type of tubes (weight, material/density and volume).
Check that loading is symmetrical by balancing the adapters and tubes used with a balance.
1. Check the maximum payload (adapter, tube and contents) for each rotor bore.
2. Load rotors and adapters only with the tubes intended for them.
3. To ensure symmetrical loading, insert sets of two tubes in opposite bores. Tubes located opposite each other must be of the same type and
contain the same filling quantity.

To keep the weight differences between the filled tubes low, we recommend taring with a balance.
This is gentle on the drive and reduces the operating noises.
5.5.2
Closing the rotor lid
Use matching rotor lids
• Fixed-angle rotors may only be used with the appropriate rotor lid for the respective rotor.
The rotor name on the rotor must correspond to the rotor name on the rotor lid.
1. Place the rotor lid vertically on the rotor.
2. Turn the rotor lid screw clockwise to seal the rotor.
