The following procedures should be performed regularly to ensure
continued performance and long service life of the centrifuge.
• Regularly inspect the interior of the rotor chamber for accumulations
of sample, dust, or glass particles from broken sample tubes. Clean as
required (see

rotor vibrations.
• Regularly check the air intake and exhaust vents for obstructions. Keep
vents clear and clean.
• Use a sponge to wipe condensation out of the chamber bowl between
runs to prevent chamber icing (refrigerated models). If chamber icing
occurs, defrost before use.
• To prevent the rotor from sticking, lubricate the drive shaft with
Spinkote at least once a month, and after each cleaning.
If the gasket (961806) around the rotor chamber opening becomes
damaged or worn, replace it as follows. (See Figure 5-1.)
1. Remove the gasket by pulling it up and away from the opening.
2. Install the new gasket by positioning the groove in the gasket over the
rim of the opening.
3. Press the gasket around the opening so that the rim is seated in the
gasket groove.
