6. Care and Maintenance
Please use water-soluble, mild detergents for cleaning. Avoid corroding or aggressive
substances. Do not use alkaline solutions or solvents or agents with abrasive particles.
Before using detergents or decontamination agents, which have not been recom-
mended by us, the user has to contact us to make sure that such procedure will not
damage the centrifuge.
Remove product particles from the rotor chamber using a cloth or paper towel. It is
recommended to open the cover when the centrifuge is not in use so that moisture
can evaporate. Increased wear of the motor bearings will thus be avoided.
If there is the risk of toxic, radioactive or pathogenic contamination, special
safety measures must be heeded.
For care of accessories special safety measures must be considered as these are
measures ensuring operational safety at the same time.
Chemical reactions as well as stress-corrosion (combination of oscillating pres sure
and chemical reaction) can affect or destroy the metals. Hardly detectable cracks on
the surface expand and weaken the material without visible signs. When detecting a
visible damage of the surface, a crack, a mark or any other change, also corrosion,
the part (rotor, etc.) must be replaced immediately.
In order to avoid corrosion, rotor incl. tie-down screw and cover seal and adapters
must be cleaned and greased regularly with the supplied anti-corrosive oil. Before
using detergents or decontamination agents which had not been recommended by
us, the user has to contact us to make sure that such procedure would not damage
the centrifuge. The rotor tie-down screw must be greased using grease.
Cleaning of accessories should be done outside of the centrifuge once a week or
preferably after every use. Adapters should be removed. After this the parts should
be dried with a soft cloth or, alternatively, in a drying chamber at approx. 50 °C.
If there is the risk of toxic, radioactive or pathogene contamination,
special safety measures must be kept.
Especially aluminium parts are extremely corrosive. A neutral cleaning detergent with
a pH-value between 6 and 8 should be used for such parts. Alkaline agents exceeding
pH 8 must be avoided. Especially aluminium parts must be greased regularly with
anti-corrosive oil. This procedure essentially increases life time and reduces corrosion.
Careful maintenance increases life time and avoids premature failure of the rotor.
Corrosion or resultant damages which are caused by insufficient care do not
constitute a warranty claim.
In case of glass breakage all glass particles must be carefully removed. Rubber inserts
have to be carefully cleaned and may have to be replaced. If a problem has occured,
the following has to be considered:
Glass particles in the rubber cushion will cause glass breakage again.
Glass particles in the centrifuge chamber will cause metal abrasion due to the strong
air circulation. This dust will not only pollute the centrifuge chamber, the rotor and
the material to be centrifuged but also damage the surfaces of the accessories, the
rotors and the centrifuge chamber.
