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 the D-AQ, D-AL or D-HV mode.

2. Then proceed as with the concentrator function (see Concentration on p. 30).

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 the V-AQ, V-AL, V-HV, D-AQ, D-AL or D-HV mode.

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

If you use the gel dryer individually, you should use the D-AQ, D-AL or D-HV modes in order

to protect the drive.

2. In contrast to the concentrator or desiccator function, 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 p. 30).

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 the CEFU mode.

2. Then proceed as with the concentrator function (see Concentration on p. 30).

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

during operation.

WARNING!

Danger of explosion from gas mixtures.

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

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

 Note the solvent properties and only carry out parallel operations with identical solvents or

solvents that evaporate in a non-hazardous manner.
