and qualified personnel. Use only original spare parts! Use only original spare parts! Use only original spare parts! Use only original spare parts! Use only original spare parts!
7.2 Maintenance and cleaning
Maintenance
The maintenance of the centrifuge involves essentially keeping the rotor
chamber, the rotor and the accessories clean. Please pay special attention to
anodized aluminium parts. Breakage of rotors can be caused even by slight
damages. In the case of rotor, buckets or tube racks contacting corrosive liquids,
the respective spots and parts have to be cleaned carefully.
Corrosive liquids are for example:
- alkaline soup-solution
- alkaline amino
- strong acids
- solutions containg heavy metals
- waterfree and chlorinated solvents
- salt solutions e.g. sea-water
Cleaning:
The purpose of a thorough cleaning is, beside hygienic reasons, the avoidance of
corrosion by soiling. In order to avoid the damage of anodized parts such as
rotors, reduction plates ect., only neutral cleaning agents with a ph-value 6-8
should be used. Never use an alkaline cleaning agents ( ph > 8 ). After cleaning
please ensure that all parts are dried thoroughly by hand or in a warm-air-cabinet
( max. temperature +50°C ).
It is recommended that all anodized aluminum parts are regularly treated with
anti corrosion oil, so that their durability will be increased and the corrosion
risk reduced.
Usually when used in a cold room, humidity and non hermetically closed
samples, may cause condensation to form. The condensation should be
removed regulary with a cloth from the rotor chamber.
Unplug the centrifuge when it is not being used, allow the chamber to reach room
temperature, and dry out the chamber with a cloth.
