Function Mode suitable for
Concentrator V-AQ (vacuum - aqueous) aqueous solutions
V-AL (vacuum - alcoholic) alcoholic solutions
V-HV (vacuum - high vapor) solutions with high vapor pressure
Desiccator D-AQ (desiccator - aqueous) aqueous solutions
D-AL (desiccator - alcoholic) alcoholic solutions
D-HV (desiccator - high vapor) solutions with high vapor pressure and
dry substances
Centrifuge CEFU (centrifuge) centrifugation at 1,400 rpm
Hint!
If possible, use modes V-AQ, V-AL, D-AQ or D-AL and/or occasionally operate the mode/vent
key during the run.
Hint!
During operation, you cannot change the set function. Instead, ventilate the rotor chamber during
the concentrator or desiccator function, while holding the mode/vent key.
