7.3. Loading the rotor
The centrifuge must be evenly loaded for it to function properly.
To ensure even loading, comply with the following rules when loading the
swing-out rotor for six tube holders:
• Opposite-located tube holders must be identical.
• Opposite-located tube holders must either be empty or loaded with samples of
the same weight.
• When centrifuging an uneven number of samples, insert a tube filled with water
as a counterbalance.
7.4. Centrifugation
If a problem occurs during operation which makes it necessary to switch off the centrifuge,
push the “OPEN/STOP” button immediately.
Procedure:
• Press “OPEN/STOP” button to unlock the lid.
• Insert sample tubes in the tube holders. Observe rules for even loading! The most recent
program selected lights up.
• Press “OPEN/STOP” button to select program.
• Close the lid and turn lid knob to end position in clockwise direction.
• Press the “START” button.
• The rotor will start to turn and the red LED in the centrifuge lights up.
