
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.

Handling of bio-safety systems

Bio-safety systems may only be used when they are dry.
Each time before using the bio-safety system, all parts of the bio-safety system must be visually inspected for
damage. In addition, the sealing ring(s) of the bio-safety system must be checked to make sure they are in the
correct installation position.
Damaged parts of the bio-safety system must be exchanged immediately.
Damaged bio-safety systems are no longer microbiologically sealed.
To ensure leak-tightness, the lid of the bio-safety system must be correctly sealed.
For the available bio-safety systems, see the chapter "Appendix, Rotors and accessories". If in doubt, you can
get the information you need from the manufacturer.
