• After the apparatus has cooled
down completely, drain the water
out of the evaporator through the
outlet valve (6). The outlet valve
(6) must remain opened!
• Hang the tubing ends of the outlet
valve (6) and
connection (5) into the vessel for
the disposal of the acid. For safety
reasons place the vessel into a
collection tray.
• Firmly screw on the protective cap
(2) on the pressure equalization
opening of the level tube (3).
• Disconnect the
tubing from the tap and insert the
funnel into the free end of this
tubing. Make sure that the funnel
fits tightly!
• Now insert the funnel in the stand.
The lower end of the funnel cone
must be on the same level as the
degassing outlet (1).
• Use the graduated jug to pour
approx. 300 ml of acetic acid (10
to 50 %) into the funnel. Be
carefully and avoid spilling!
