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.
