• 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 (Allegra X-12R).
• 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 before each run.
• Leave door open between runs.
• Set temperature to a setting higher than
ambient temperature.
• Turn centrifuge power off.
