Concentrator plus/Vacufuge® plus — Operating manual

5 Operation

5.1 Overview of operating controls

Before using the device for the first time, familiarize yourself with the operating controls and the

device display. A depiction of the operating controls and device display can be found on the

fold-out page (see Fig. C).

5.2 Functions

Concentrator plus and Vacufuge plus can be used as a concentrator, a desiccator or a centrifuge.

For the concentrator and desiccator functions, there are three different modes available for the

quick concentration of different solvents:

 To set the desired function, press the mode/vent key before operation of the device.

1 Concentration run time

1 min to 9:59 h, infinitely (oo), adjustable in 1 min

increments.

2 Braking function

and held. Ventilation is displayed.

9 Setting the temperature 10 Setting the braking function

11 Setting the concentrator run time

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 min

-1

Hint!

Use the V-AQ, V-AL, D-AQ or D-AL modes if possible, or press the mode/vent key from time to

time during the run.

Hint!

During operation, you cannot change the set function. Instead, holding the mode/vent key during

the concentrator or desiccator function ventilates the rotor chamber.
