Filling the evaporation flask:
You can fill the evaporation flask manually prior to creating the
vacuum. The evaporation flask should not be filled more than half
its volume.
The maximum allowed load (evaporation
CAUTION
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!
