Maintenance and Care
4. 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. Only exception is the hematocrit rotor at 134 °C for 20 min. Refer to "Rotor
Specifications" on page 17 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 (521-1769).
CAUTION
Never exceed the permitted temperature and duration when autoclaving.
NOTICE
No chemical additives are permitted in the steam.
4. 7. Service
VWR International recommends having the centrifuge and accessories serviced once a
year by an authorized service technician. The service technician checks the following:
 electrical equipment and connections
 suitability of set-up site
 centrifuge lid lock and safety system
 rotor
 fixation of rotor and drive shaft of the centrifuge
 protective casing
Before service, centrifuge and rotors should be thoroughly cleaned and decontaminated to
ensure full and safe inspection can be completed.
VWR International offers inspection and service contracts for this work. Any necessary
repairs are performed for free during the warranty period and afterwards for a charge. That
is only valid if the centrifuge has only been maintained by an authorized VWR International
service technician.
A validation of the centrifuge is recommended and can be ordered from customer service.
4. 8. Lifetime
The centrifuge is specified for a lifetime of 13 years. Decommissioning the centrifuge is
suggested when this limit is reached.
The lifetime of rotors, buckets and lids is based on cycles and specified individually for each
rotor in the chapter "Rotor Specifications" on page 17. Other accessories are not limited
by a specific lifetime and need only be replaced when damaged or worn.
