TM
Frontier 2000 Centrifuges
Clean all accessible areas of the device and its accessories, including the power cord with a damp
5.
cloth.
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
7.
components of 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.
Control the unit and accessories for damage.
9.
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 directly after the run. Rotors may be autoclaved at a maximum temperature of 121°C.
4.1.5 Disinfection of PP-rotors
Autoclaving
The recommended time for autoclaving: 15 – 20 min at 121°C (1 bar)
ATTENTION:
The sterilization time of 20 min. must not be exceeded. Repeated sterilization will cause
reduction of the mechanical resistance of the plastic material
Before autoclaving the PP-rotor and adapter must be thoroughly cleaned to avoid the burning in of dirty
residues. You can disregard the consequences of some chemical residues to plastic materials at
ambient temperatures. But at the high temperatures during autoclaving those residues may corrode and
destroy the plastic. The objects must be thoroughly rinsed with distilled water after the cleaning but
before the autoclaving. Residues of any cleaning liquids may cause fissures, whitening and stains.
Gas sterilization
Adapters, bottles and rotors may be gas sterilized with Ethylenoxyd. Make sure to air out the items after
the sterilization and before using them again.
ATTENTION:
Because the temperature may rise during the sterilization, rotors, adapters and bottles
must not be closed and must be totally unscrewed.
Chemical sterilization
Bottles, adapters and rotors may be treated with the usual liquid disinfectants.
ATTENTION:
Before applying any other cleaning or decontamination method than recommended by
the manufacturer, contact the manufacturer to ensure that it will not damage the unit or the
rotor.
