Rotors and accessories with limited term of use

The use of specific rotors, suspensions and accessories is time limited.
They are marked with an expiry date, e.g. "einsetzbar bis Ende: / usable until end of: V. Quartal 2011" (applicable
until the end of: Vth quarter 2011).
The rotors, suspensions and accessories may not be used for longer periods for safety reasons once the
marked expiry date has been reached.
26.3

Autoclaving

Swing-out rotors, angle rotors made of aluminium, suspension made of metal, lids with biodegradable seals as well
as stands and reductions can be autoclaved at 121° C / 250°F (20 mins).
Otherwise you must ask the manufacturer.
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.
After autoclaving, we recommend that the sealing rings of the aerosol-tight and bio-safety systems be
exchanged.
26.4

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.
