/// Fill the evaporation flask
�
The unit is ready for service when the mains plug has been plugged in�
�
Use the power switch to switch on or off the device�
Adjust the speed by turning the speed adjusting knob� The scale from 1 to 10 corresponds to
a speed range of 20 to 300 rpm under nominal load�
Notice:
Make sure that the speed adjusting knob is in the “0” position when switching on the
power switch, otherwise a warning sound will be given�
Manual filling:
You can fill the evaporation flask manually prior to creating the vacuum� The
evaporation flask should not be filled more than half its volume�
Automatic filling:
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 back feed 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�
Notice:
The maximum allowed load (evaporation flask and contents) is 3 kg�
