Risk of injury from glass splinters, chemical reactions (sol-
vent with heating medium), solvent, and hot liquids.
Evaporation flask and flask nut may collide with the wall or base of
the heating bath during lowering and become damaged (glass
breakage).
Always monitor lowering of the evaporation flask. (If nec-
essary, adjust the heating bath position, inclination, and
immersion depth to the size of the evaporation flask).
Adjust the immersion depth of the evaporation flask using the
terminal (see Chapter 8, Operating the rotary evaporator).
In the event of power failure, in the interest of safety, the evapora-
tion flask will automatically lift out of the heating bath to its upper
endpoint.
If needed, install the refilling valve (see Chapter 11, Spare
parts and accessories) (see Fig. 6):
Fig. 6: Position of drip washer
1. Slide the PTFE tube (1) onto the refilling valve's (2) corre-
sponding glass fitting.
2. Slide the drip washer (3) onto the PTFE tube (1).
3. Insert the PTFE tube (1) through the chilled condenser and
into the evaporation flask.
Ideally, the drip washer (3) will rest on the insertion tube
(see Fig. 6).
4. Position the refilling valve (2) and securely tighten the un-
ion nut. The refilling valve is now installed.
