Potential Damage
Gouges or corrosion on
surface of rotor
Septa damage in
continuous flow or zonal
rotor
Light scratches on surface
Bent centrifuge spindle
Corrosion, pitting and even minor surface imperfections affect metal rotor life by increasing stress and,
as a result, make it difficult to predict at what point the rotor material could fail.
Maintenance and Care
Metal corrosion can be avoided by following a routine maintenance program after each rotor use:
• Clean rotors, lids, adapters and any associated parts with a neutral cleaning agent with a pH value
between 6 and 8. Rinse with distilled water and dry thoroughly with a soft cloth.
• Do not use strong alkaline laboratory detergent on aluminum rotors; if encrusted material is present,
remove it with a soft, twisted-bristle brush and the 1 % non-alkaline soap solution.
• For benchtop, lowspeed and superspeed swinging bucket rotors, keep the bucket trunnion pins
clean and lubricated.
• Lubricate o-rings with vacuum grease and metal rotor threads with anti-galling grease (75003786)
weekly, when specified in rotor manual.
• Apply an additional coating of anti-corrosion oil (70009824) to prolong the life of an anodized
coating.
• Refer to the Maintenance and Care chapter in this rotor manual.
Storage
Any moisture left on a metal rotor can initiate corrosion, so after cleaning ensure proper storage:
• Remove all adapters from rotor cavities when not in use.
• Dry and store upside-down Use a PTFE-coated or plastic matting to allow for airflow or a
ventilated shelf to avoid gathering condensation in the cavity or bucket bottom.

Preventive Measures
• Inspect before every use.
• Avoid sharp impact.
• Avoid harsh chemicals
• Clean the surface of rotor and coat with
a thin layer of oil to prevent corrosion.
• Avoid banging or dropping.
• Never use metallic objects to remove
debris.
• Remove rotor in a straight up motion.
• Ensure samples are properly balanced
