Maintenance and Care
5. 6. Autoclaving
Always disassemble all parts before autoclaving, e.g. lids need to be removed before autoclaving a bucket or
rotor.
If not stated otherwise on the parts themselves, all parts can be autoclaved at 121 °C for 20 min. Refer to
“Rotor
Specifications” on page B-1 for details on rotors.
Make sure that the necessary sterility is achieved according to your requirements.
After autoclaving, treat the entire surface of aluminum parts including the cavities with corrosion protection oil
(70009824).
Treat the bolts of swing out rotors with bolt grease (75003786) if necessary.
CAUTION Never exceed the permitted temperature and duration when autoclaving.
NOTICE No chemical additives are permitted in the steam.
5. 7. Maintenance
Lifetime
The centrifuge is specified for a lifetime of 10 years. Decommissioning the centrifuge is suggested when this
limit is reached.
The lifetime of a rotor and buckets depends on the amount of physical load. Do not use rotors and buckets that
exceed the maximum number of cycles. The maximum number of cycles for rotors and buckets is given in the
chapter
“Rotor Specifications” on page B-1 . The maximum number of cycles for buckets is marked on the
buckets themselves. Fiberlite rotors are not limited in cycles, but have a limited lifetime of 15 years.
Preventive Maintenance
In order to keep this product able to perform the intended applications reliably and safely, ongoing preventive
maintenance is necessary in accordance with the following recommended schedule:
ƒ
The anti-vibration mounts (20038955) and the motor cover (20058551) need to be replaced every 3 years.
ƒ
The gas spring (50154683) and the particle deflection seal (50154683) need to be checked annually and
replaced if necessary. Refer to
Figure 2–1 on page 2-1
ƒ
For rotors and buckets mind the information in “Rotor and Accessories Inspection” on page 5-1 .
CAUTION Usage beyond these limits might affect the safety of the overall system.
NOTICE
