4. MAINTENANCE

4.1 Maintenance and cleaning

4.1.1 General Care

Maintenance of the centrifuge is confined to keeping the rotor, the rotor chamber and the rotor
accessories clean as well as to regularly lubricating the rotor insert bolts of a swing out rotor (if
available).
The most suitable lubricant is the High TEF oil.
Lubricants containing molycote and graphite are not allowed.
Please pay special attention to anodized aluminum parts. Breakage of rotors can be caused even by
slight damage.
In case of rotors, buckets or tube racks getting in touch with corrosive substances the concerned spots
have to be cleaned carefully.
Corrosive substances are for instance: alkalis, alkaline soap solutions, alkaline amines, concentrated
acids, solutions containing heavy metals, water-free chlorinated solvents and saline solutions. e.g. salt
water, phenol, halogenated hydrocarbons.
Cleaning – units, rotors, accessories:
Turn the device off and disconnect it from the power supply before you begin any cleaning or
disinfecting. Do not pour liquids into the housing interior.
Do not spray disinfectant on the device.
Thorough cleaning not only has its purpose in hygiene but also in avoiding corrosion due to pollution.
In order to avoid damaging anodized parts such as rotors, reduction plates etc., only pH-neutral
Detergents with a pH-value of 6-8 may be used for cleaning. Alkaline cleaning agents (pH-value > 8)
must not be used.
After cleaning, please ensure all parts are dried thoroughly, either by hand or in a hot-air cabinet
(max.Temperature + 50°C).
It is necessary to coat anodized aluminum parts with anti-corrosion oil regularly in order to increase their
life- spans and reduce corrosion predisposition.
Due to humidity or not hermetically sealed samples, condensate may be formed. The condensate has to
be removed from the rotor chamber with a soft cloth regularly.
The maintenance procedure has to be repeated every 10 to 15 runs, or at least once
a week.
Connect the unit to the power supply, after the equipment is completely dry.
Do not carry out disinfection with UV-, beta- and gamma-rays or other high energy radiation.
Metal rotors can be autoclaved.
Rotor lid and adapters can also be autoclaved (max. 121°C, 20 min).
The tube racks are made of PP and cannot be autoclaved at 134°C.

4.1.2 Cleaning and disinfection of the unit
