Sterilization and Disinfection

When sterilization or disinfection is a concern, consult your laboratory safety officer regarding
proper methods to use. While Beckman Coulter has tested the following methods and found that
they do not damage the rotor or components, no guarantee of sterility or disinfection is expressed
or implied.
• Rotors and most rotor components (except those made of modified polyphenylene oxide) can
be autoclaved at 121°C for up to an hour. Remove the lid and place the rotor (and/or buckets)
in the autoclave upside-down. (O-rings and gaskets can be left in place on the rotor.)
• Ethanol (70%) may be used on all rotor components, including those made of plastic. Bleach
(sodium hypochlorite) may be used, but may cause discoloration of anodized surfaces. Use the
minimum immersion time for each solution, per laboratory standards.
CAUTION
Ethanol is a flammability hazard. Do not use it in or near operating centrifuges.

Inspection

Frequent and thorough inspection is crucial to maintaining a rotor in good operating condition.
• Periodically (at least monthly, depending on use) inspect the rotor, especially inside cavities
and buckets, for rough spots, cracks, pitting, white powder deposits on aluminum rotors
(frequently aluminum oxide), or heavy discoloration. If any of these signs are evident, do not
run the rotor. Contact your Beckman Coulter representative for information about the Field
Rotor Inspection Program and the Rotor Repair Program.
• Regularly check the condition of O-rings or gaskets and replace any that are worn or damaged.
• Regularly check that all sealing surfaces are smooth and undamaged to ensure proper sealing.

Before each use, inspect Aeroseal cover sealing surfaces,
especially the O-ring groove. It must be smooth and free of

scratches. Also ensure that the top 2.54 cm (1 in.) of the
(343685)
bucket is clean and smooth; buckets with scratches or

gouges in this surface will not seal properly. Inspect the
