If less than the maximum complement of samples is loaded, the tubes must be placed in opposite pockets.
An odd number of tubes requires an additional blank, water-filled tube of identical total weight to balance.
Significant vibrations can damage the accessories, the unit and the samples. Most vibration is caused by
incorrect loading of the tubes. For this reason, the centrifuge is equipped with an imbalance detector.
In case of excessive imbalance, the load imbalance indicator LED is illuminated and the brake is applied
immediately. The rotor will be decelerated to rest in few seconds.
As soon as the motor stops, open the centrifuge and redistribute the samples to produce an equal weight on
diametrically opposite sides.
Also remember that the pins must be softly lubricated. Inadaquate lubrication of the pins may cause
incorrect swinging of the buckets resulting in imbalance phenomen. See chapter 6.6 for details.
If the message persists, despite your efforts to balance the load, call your Thermo Service representative.
