Loading the rotor

Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2).

Check the rotor for firm seating.

The rotors must be loaded symmetrically. The centrifuge containers have to be distributed evenly on all rotor
positions. For authorised combinations see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and
accessories".
Example:
Rotor is evenly loaded

The centrifuge containers may only be filled outside of the centrifuge.

The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
The centrifuging vessels may only be filled so
far that no fluid can be expelled from them
while the centrifuge is running.

When loading the rotor, no liquid may enter the rotor or the centrifuging chamber.

In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.

The weight of the permissible filling quantity is specified on each rotor. This weight may not be exceeded.

Closing biosafety systems

In order to guarantee that it is sealed, the lid to the biosafety system has to be firmly closed.
In order to prevent the packing ring from twisting when opening and closing the cover, the packing ring must
be lightly rubbed with talcum powder or a rubber care product.
For further details of available biosafety systems see chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors
and accessories". If in doubt, you should obtain relevant information from the manufacturer.
Lid with screw closure and turning handle
