Connect PTFE tube Ø 6 mm to
connection (1) and tighten until hand-
tight.
Route PTFE tubes and flask sensor into the evaporating flask and secure the multiple
screw connection at connection (4) until hand-tight.
Multiple screw connection
Route PTFE tube Ø 8 mm through connection (2) (only on Distimatic including
automatic drainage of residue) and PTFE tube Ø 6 mm through connection (3) and
secure in place so it is hand-tight.
The immersion depth of the PTFE tubes and the flask sensor in the evaporating flask
may be determined by loosening the respective screw cap slightly at the multiple
screw connection and by pulling or pushing the PTFE tube or the flask sensor.
Re-secure the screw caps on the multiple screw connection so they are hand-tight
again afterwards.

Optimization of the distillation process
Refill evaporating flask only up to one third. Position the flask sensor
accordingly.
Use large evaporating flasks (3-5 liter variants) whenever possible.
Use the following recommended immersion depths:
The end of the PTFE tube (5) Ø 6 mm varies. Flask sensor (6) ends just
above the required maximum fill level. PTFE tube (7) Ø 8 mm (only on
Distimatic including automatic drainage of residue) ends approximately
2 – 3 mm above the bottom of the evaporating flask.
This way your distillation process will become much faster.
