3. MAINTENANCE

Maintenance:

Maintenance of the centrifuge is dependent on prolonging the life of the rotor, the rotor chamber and

the rotor accessories.

Don´t use acid detergents and/or burnished polish.

Breakage of rotors can be caused by the slightest damages.

In case of metallic rotor parts or the motor shaft becoming in touch with corrosive substances, the

affected area must be cleaned, thoroughly.

Corrosive substances, such as, must be avoided: alkalis, alkaline soap solutions, alkaline amines,

concentrated acids, solutions containing heavy metals, water-free chlorinated solvents, saline

solutions, e.g. salt water, phenol, halogenated hydrocarbons.

Maintenance – Unit, Rotor, Accessories:

Turn the device off and disconnect from the power supply, before beginning any cleaning or

disinfecting. Do not pour liquids into the housing interior.

Spray disinfectant on the device.

Thorough cleaning not only has its purpose in hygiene, but also in avoiding pollution based

corrosion.

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 must not

be used, (pH-value > 8).

After cleaning, please ensure all parts are dried thoroughly, either by hand or in a hot-air cabinet

(Max. Temperature + 50°C/122°F).

It is necessary to coat anodized aluminium parts with anti-corrosion oil regularly, in order to

increase their life-span and reduce corrosion predisposition.

Due to humidity or not hermetically sealed samples, condensation may form. The condensation

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, but at least once at week!

Connect the unit to the power supply, after the equipment is completely dry.

Do not implement disinfection with UV-, beta- and gamma-rays or other high energy radiation.
