22.3 Autoclaving
Swing-out rotors, angle rotors made of aluminium and accessory parts can be autoclaved at 121°C (20 min).
The lids of the rotors and containers must be removed prior to autoclaving.
Autoclaving accelerates the ageing process of plastics. In addition, autoclaving may discolour plastics.
22.4 Centrifuge
containers
•
With leakiness or after the breakage of centrifuging containers broken container parts and leaked centrifugation
material are to be completely removed.
•
The rubber inserts as well as the plastic sleeves of the rotors are to be replaced after a glass breakage.
Remaining glass splitters cause further glass breakage!
•
If this concerns infectious material, a disinfection process is to be executed immediately.
23 Faults
