6.2
Assembling the Snap Flange Coupling
•
Insert the snap flange coupling from above, until the pins
in the lock latch into the hole on the lug.
•
Close the two segments of the snap flange coupling.
•
Turn the snap flange coupling again by 180°, until the closure
lies at the top.
•
Lift the two segments of the snap flange coupling to open
them.
•
Lay the neck of the glass flask into the middle segment
and raise the flask slightly.
•
Pull the segment on the left back slightly and close it until
the hook latches in place.
•
Close the segment on the right.
•
Insert the closure hook and close the snap flange coupling
with the closure lever. A clear resistance must be felt when
doing this. Otherwise no seal can be fully guaranteed.
6.3
Removing the Evaporating Flask Seal
•
Seal the holder for the seal by 180°, until the opening faces
up.
•
Take hold of the seal with both hands, from above and
from the front, and pull it out slowly.
•
Tilt the seal slightly and carefully pull it all the way out. Be
careful not to damage the glass centering bulge when
doing so.
•
Remove the vapor duct.
