Care and Maintenance

NOTE
Accumulations of dust or other foreign matter can damage rotor pins (resulting in rotor vibrations). To
prevent this, clean the centrifuge bowl daily. Spray the centrifuge bowl with an antistatic solution and
wipe it clean.

Inspection

• Periodically (at least monthly) inspect the rotor yoke, buckets, and/or multiwell plate carriers,
especially inside cavities, for rough spots or pitting, white powder deposits — 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 center.
• Regularly check the condition of the O-ring (927571) in the tie-down nut; if it is worn or
damaged, replace it.
• Regularly check the condition of the Micro Plus plate carrier base (361302) and pad (362390) and
do not use them if there are visible signs of damage.

Maintenance

Buckets and Micro Plus carriers are made of anodized aluminum. Do not use sharp tools on them, as
scratches in the anodized surface may lead to corrosion.
• Approximately once a week, and after cleaning and/or autoclaving, wipe the rotor pins and pin
sockets (see
Allow the lubricant to dry for at least 5 minutes before installing the rotor in a centrifuge.
• Before using the tie-down nut (366642), check it for damage such as distortion, splitting, or
stripped threads; replace it if it is damaged. Inspect the O-ring (927571) in the base of the nut
for cracks, replace if damaged. Do not use any type of lubricant or grease on the threads of the
tie-down nut.
• Before first use of the rotor, and after washing, apply Anti-Seize (961660) to the rotor yoke drive
hole as described under Cleaning, below.
