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
Open the lid before you turn off the unit. Disconnect it from the power supply.
1.
Open the rotor nut by turning the rotor key counter clockwise.
2.
Remove the rotor.
3.
4.
For cleaning and disinfection of the unit and the rotor chamber use the above mentioned cleaner.
Clean all accessible areas of the device and its accessories, including the power cord with a damp cloth.
5.
Wash the rubber seals and rotor chamber thoroughly with water.
6.
Rub the dry rubber seals with glycerol or talc to prevent these to becoming brittle. Other components of
7.
the unit, e.g. the lid lock, motor shaft and rotor must not be greased.
Dry the motor shaft with a soft, dry and lint-free cloth.
8.
9.
Control the unit and accessories for damage.
Make sure that the centrifuge is turned off the unit and disconnect the unit from the power supply. Then
remove adherent dust from the ventilation slots in the centrifuge by using a soft brush. Do this at least every
six months.
WARNING :
Electric Shock Hazard. Disconnect the equipment from the power supply before cleaning.
Make sure that no liquid enters the interior of the equipment.
4.1.3 Cleaning and disinfection of the rotor
1.
Clean and disinfect the rotors, rotor lids and adapters with the above mentioned cleaner.
2.
Use a bottle brush to clean and disinfect the rotor bores.
3.
Rinse the rotors, rotor lid and adapter with clear water. Particularly the drillings of angle rotors.
4.
For drying of the rotors and accessories set them on a towel. Place the angle rotors with bores down.
5.
Dry the rotor cone with a soft, dry and lint-free cloth and look for damage. Do not grease the rotor cone.
4.1.4 Disinfection of aluminum rotors
In case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be disinfected
