4. MAINTENANCE AND CLEANING OF
THE CENTRIFUGE
4.1 REGULAR SERVICE
We recommend having the centrifuge and associated rotors checked by authorized
service at least once a year. You must thoroughly clean and disinfect the centrifuge
prior to service.
4.2 CLEANING THE CENTRIFUGE
After every centrifugation, please remove any condensed water from the rotor
chamber using a soft, absorbent cloth. After use, leave the centrifuge lid open, so the
inside can dry out. For regular cleaning of the outside surface of the centrifuge and
the rotor chamber, use mild neutral detergent and soft cloth. Make sure that no liquid
penetrates the inside of the housing. Open the lid of the centrifuge and turn off the
main switch. Disconnect the power cord from mains socket. Remove the rotor with
rotor key. Clean all accessible surfaces of the device and accessories at least once a
week and every time, when contaminated. After cleaning with detergent, the rubber
seal around the rotor chamber should be thoroughly cleaned with water and lubricat-
ed with glycerine, to prevent it from becoming brittle.
For cleaning and disinfection, use only neutral cleaners and disinfectants. Before clean-
ing or decontaminating the centrifuge, using means and methods not recommended
in this manual, you should consult with the manufacturer, in order to avoid the dam-
age to the centrifuge. To ensure safe and long operation of the centrifuge, please avoid
the use of aggressive chemicals, which can damage the centrifuge, rotor and accesso-
ries. Please check them regularly for damage caused by corrosion.
4.3 CLEANING THE ROTOR
The rotor and accessories must be regularly cleaned to prevent contamination and
corrosion caused by residue. Check the rotor and accessories monthly. This applies in
particular to the rotor bores. For cleaning the rotor use a neutral cleaning liquid. This
will protect the rotor and extend its service life.
Do not use damaged rotors and accessories for centrifugation!
To avoid the damage to the rotor, replace the sealing rings regularly.
4.4 ROTOR STERILIZATION
The rotors are autoclavable at the temperature of 121°C, for 20 minutes. After the
rotor has been autoclaved for a maximum of twenty times, seals of the rotor must be
replaced (this is valid for rotors with seals).
