5.5 User instructions on rotors
5.5.1 A-2-VC
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. 40).
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. 40).
CAUTION! Wait for rotor to stop.
During the post-run phase of Rotor A-2-VC, the device lid may open before the rotor has come
to a stop if the plates are fully loaded.
Always wait for a rotor stop to open the lid and remove the plates or tubes.
NOTICE! If handled incorrectly, the rotor can fall over.
The swing-bucket rotor may fall if the buckets are used as handles.
Remove the buckets before inserting and/or removing a swing-bucket rotor.
Always use both hands to carry the rotor cross.
WARNING! Danger of explosion from gas mixtures.
When running several devices in parallel on a vacuum system or in combination with a gel
dryer, an explosive gas mixture can develop in the vacuum system.
Observe the solvent properties. Only carry out parallel operations with identical solvents or
solvents that evaporate in a non-hazardous manner.
