5 Operation

Concentrator plus / Vacufuge® plus — Operating manual

5.6 Special function

5.6.1 Operation as a desiccator

With the desiccator function the rotor chamber is evacuated. However, the rotor is not turned.

You can place the sample tubes directly in the rotor chamber without a rotor or insert them into a

rotor.

1. mode/vent: select mode D-AQ, D-AL or D-HV.

2. Then proceed as with the concentrator function (see Concentration on page 27).

5.6.2 Operation with gel dryer

On a complete system with a gel dryer connection, a gel dryer can be run in parallel to the

operation as a concentrator and/or desiccator or used individually.

1. mode/vent: select mode V-AQ, V-AL, V-HV, D-AQ, D-AL or D-HV.

We recommend the modes V-HV and D-HV.

If the gel dryer is run individually, you should use modes D-AQ, D-AL or D-HV to protect the

drive.

2. In contrast to the concentrator or desiccator function, please open the tap of the gel dryer

connection before operation (→ knob points in flow direction) and close it again after

operation.

When the gel dryer is operated without concentrator or desiccator function the device lid must

also be closed as a vacuum cannot be generated otherwise.

3. Then proceed as with the concentrator function (see Concentration on page 27).

5.6.3 Operation as a centrifuge

With the centrifuge function, the rotor is turned. However, the rotor chamber is not evacuated.

1. mode/vent: select mode CEFU.

2. Then proceed as with the concentrator function (see Concentration on page 27).

As there is no vacuum applied in this operating mode, the mode/vent key does not have any

function during operation.

CAUTION!

Caution! Note solvent properties.

When running several devices in parallel on a vacuum system and/or in combination with a gel

dryer, an explosive gas mixture can develop in the vacuum system.

 Only carry out parallel operations with identical solvents or solvents that evaporate in a

non-hazardous manner.
