Fitting It to a Flask
Lay the disc flat over the mouth of the flask, then drop a Gooch crucible or small funnel into the collar. Once suction starts, outside air presses the disc down on the rim and the crucible down into the taper, so both joints close without clamps. Wet the rubber lightly if a crucible does not seat evenly.
Disc or Cone Adapter?
A cone adapter has to match the bore of the flask neck. This disc rests on top of the rim instead, so one piece serves flasks with different necks, provided the rim is narrower than the 75 mm base. It is sold as the rubber piece alone.
