Perform the following procedures regularly to ensure satisfactory
performance and long service life of the ultracentrifuge.
• At least once a week (depending on usage) inspect the interior of
the rotor chamber for accumulations of foreign matter. Clean as

result in rotor vibrations.
• Regularly check the stator pad for ease of rotation. Rotate it on the
stator, using light finger pressure, to ensure it moves easily. Also
check for dirt or oil; clean with alcohol
circles on the bottom).
• Regularly check the stator pad for wear; a worn pad is smooth and
shiny on the upper half of the inside surface. A shiny pad has lost
its cushioning effect and will eventually cause rotor failure.
Replace a worn pad.
➠
NOTE
Proper deceleration of the rotor (that is, allowing
the rotor to come to a complete stop before
opening the door) will increase pad life.
➠
NOTE
Before using any cleaning or decontamination
methods except those recommended by the
manufacturer, users should check with the
manufacturer that the proposed method will not
damage the equipment.
Frequent cleaning will ensure proper operation and prolong the life
of the ultracentrifuge. Always clean up spills when they occur to
prevent corrosives or contaminants from drying on component
surfaces. (Be careful not to spill liquid on the instrument where
electrical or mechanical components could become damaged.)
Refer to Chemical Resistances (publication IN-175) for chemical
compatibilities of cleaning materials.
