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 cor-
rect installation position.
Damaged parts of the bio-safety system must be
exchanged immediately.
Damaged bio-safety systems are no longer microbiologi-
cally sealed.
To ensure leak-tightness, the lid of the bio-safety system
must be correctly sealed.
Available bio-safety systems can be found in the attach-
ment
Appendix A ‘Rotors and accessories’ on page 86.
If in doubt, you can get the information you need from the
manufacturer.
