Maintenance and service
The centrifuge, rotor, and accessories are subject to high mechanical
stress. Thorough maintenance performed by the user extends the service
life and prevents premature failure.
CAUTION
If corrosion or other damage occurs due to improper care, the
manufacturer cannot be held liable or subject to any warranty claims.
• Use soap water or other water-soluble, mild cleaning agents with a pH
value between 6 and 8 for cleaning the centrifuge and accessories (see
also chapter 8.2 - "Sterilisation and disinfection of the rotor chamber
and accessories").
• Avoid corrosive and aggressive substances.
• Do not use solvents.
• Do not use agents with abrasive particles.
• Do not expose the centrifuge and rotors to intensive UV radiation or
thermal stress (e.g. by heat generators).

Maintenance
8.1.1
Centrifuge
• Unplug the mains power plug before cleaning.
• Carefully remove all liquids, including water and particularly all the
solvents, acids, and alkaline solutions from the rotor chamber using a
cloth in order to avoid damage to the motor bearings.
• If the centrifuge has been contaminated with toxic, radioactive, or
pathogenic substances, clean the rotor chamber immediately with a
suitable decontamination agent (depending on the type of
contamination).
WARNING
Take suitable precautions for your own safety if there is a risk of toxic,
radioactive, or pathogenic contamination.
• After every cleaning process, grease the motor shaft slightly with a
small amount of heavy-duty grease for load-bearing bolts (part no.
71401) and distribute the grease with a cloth so that it forms a thin
layer.
