
The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
In the case of angle rotors, 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 angle rotors, no liquid may get into the angle rotors or centrifuging chamber.

When loading the hangers and swing-out rotors and when swivelling out the hangers while the centrifuge is
running, no liquid may enter the hangers 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.

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.
If the hanger of a biosafety system is used without the lid, the packing ring must be removed from the hanger
in order to prevent the packing ring from being damaged during the centrifugation run. Damaged packing rings
must not be used to seal the biosafety system.
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.
