Loading the rotor

•
The rotors and hangers may only be loaded symmetrically. For authorised combinations see Chapter
"Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories".
•
Always fill the centrifuge containers outside of the centrifuge.
•
In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.
•
The weight of the permissible filling quantity is specified on each rotor. This weight may not be exceeded.

Aerosol tight sealing of angle rotors

To ensure aerosol sealing the lid of an aerosol sealed angular rotor must be firmly closed.
This is performed with the help of the supplied spanner that is inserted through the borehole
in the rotary handle. If the rotary handle does not have a borehole then the lid must be firmly
closed by turning in clockwise direction.
For available aerosol tight angle rotors, please see chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories".

13.1

Control knob

For setting the individual parameters.
Turning anticlockwise reduces the value. Turning clockwise increases the value.
13.2

Control panel pushbuttons (keys)

•
Selection control key for selection of specific parameter.
SELECT
The subsequent parameter is selected by every further keystroke.
•
Start centrifugation run. The LED in the button lights up during the centrifugation run as long as the
START
rotor is turning.
IMPULS
•
Short-term centrifugation.
The centrifugation run is effected as long as the button is held down. The LED in the button lights up
during the centrifugation run as long as the rotor is turning.
•
Store inputs and changes.
•
End centrifugation run.
STOP
The rotor runs down with a pre-selected brake step. The right-hand LED in the button lights up until the
OPEN
rotor is stationary. Once the rotor is stationary the left-hand LED flashes in the button. Pressing the
button twice triggers the EMERGENCY STOP.
•
Open lid.
The left-hand LED in the button goes out.
•
Leave the parameter input.
•
Switch between RPM and RCF display.
RCF
RCF values are displayed in > <.
•
Start pre-cooling.
The pre-cooling speed is settable. It is pre-adjusted to 10000 RPM.
