extended power failure, it may be necessary to trip the door-locking mechanism manually to
remove the rotor and retrieve your sample.

• Precool or prewarm rotors before running at low
or high temperatures.
• Precool rotor chamber by running a 30-minute
cycle at the required temperature with the
speed set at 2000 RPM.
• Make sure the air intake vent is clear.
• If using multiwell-plates for runs exceeding
2 hours in a warm and/or humid environment,
speed reduction may be required to maintain
low sample temperature.
Wipe out moisture from the chamber and the
chamber gasket before each run.
• Leave door open between runs.
• Set temperature to a setting higher than
ambient temperature.
• Turn centrifuge power off.
