The maximum allowed load (evaporation flask and contents) is 3 kg.
Filling medium by vacuum: prior to filling the evaporation flask, a vacuum controller is used to regulate the
glass apparatus to the target pressure.
- Now fill the evaporation flask using the backfeed line.
- Due to the vacuum present, the solvent is suctioned into the evaporation flask. This enables you to keep
solvent loss due to suctioning to a minimum.
Setting up the heating bath:
Also refer to the operating instructions for the HB 10 heating bath!
- Move the lift to the bottom position and check the position of the heating bath in relation to the evaporation
flask. When using larger evaporation flasks (2 or 3 liters) or depending on the angle of the rotation drive, you
can move the heating bath to the right.
- Fill the heating bath with the tempering medium until the evaporation flask is surrounded by tempering
medium to 2/3 of its volume.
- Switch on the rotation drive and slowly increase the speed.
Note: Avoid creating waves.
- Switch on the heating bath using the main on/off switch.
Note: Avoid stress on the glass due to different evaporation flask and heating bath temperatures when
lowering the evaporation flask into the heating bath!
