Maintenance and Care
3. Cleaning
CAUTION
Before using any cleaning methods, users should check with the manufacturer of the cleaning agents that
the proposed method will not damage the equipment.
CAUTION
Drive and door lock can be damaged by entering liquids. Do not allow liquids, especially organic solvents, to
get on the drive shaft, the drive bearings or the centrifuge door locks.
Organic solvents break down the grease in the motor bearing. The drive shaft could lock up.
Clean as follows:
1. Clean rotor, buckets and components outside of the centrifugation chamber.
2. Separate rotor, buckets, lids, adapters and tubes to allow thorough cleaning.
3. Rinse rotor and all components with warm water and a neutral detergent that is suitable for use with the materials. If in
doubt contact the manufacturer of the cleaning agent. Clean away the grease from the rotor trunnions (pivot point for
swinging buckets).
4. Use a soft brush without metal bristles to remove stubborn residue.
5. Rinse rotor and all components with distilled water.
6. Place the rotors on a plastic grate with their cavities pointing down, to enable the cavities to fully drain and dry.
7. Dry all of the rotors and components after cleaning with a cloth or in a warm air cabinet at a maximum temperature of 50 °C.
If drying boxes are used, the temperature must never exceed 50 °C. Higher temperatures could damage the material and
shorten the lifetime of the parts.
8. Inspect the rotor and components for signs of damages.
9. After cleaning, treat the entire surface of aluminum parts including the cavities with corrosion protection oil (70009824).
Treat the bolts of the swing out rotor with bolt grease (75003786).
