Plastic Parts
Check for signs plastic crazing, fading, bruising or cracking.
CAUTION Do not run any rotor or accessories with sign of damage.
Ensure that the rotor, buckets and accessories are within the service life and number of cycles.
It is recommended that you have rotors and accessories inspected yearly as part of your
routine service to ensure safety.
Cleaning
CAUTION Before using any cleaning methods except those recommended by the
manufacturer, users should check with the manufacturer of the cleaning agents that the
proposed method will not damage the equipment.
Clean as follows:
1. Clean rotor, buckets and accessories outside of the centrifuge bowl.
2. Separate all rotors, buckets, lids, adapters and tubes to allow thorough cleaning.
3. Rinse rotor and all accessories with warm water and a neutral detergent that is suitable for use with
the materials. If in doubt contact the manufacturer of the cleaning agents. Ensure grease on rotor
trunnions (pivot point for swinging buckets) is cleaned away.
4. Use a soft brush without metal bristles to remove stubborn residue.
5. Rinse rotor and all accessories with distilled water.
6. Place the rotors on a plastic grate with their cavities pointing down, to allow to fully drain and dry.
7. Dry all of the rotors and accessories 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, since higher temperatures could damage the material and shorten the lifetime of the parts.
Once clean and dry, inspect the rotor and accessories.
After cleaning, treat the entire surface of aluminium parts including the cavities with corrosion
protection oil (521-1769).
Treat the bolt of the swing out rotor with bolt grease (521-1770).
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.
