This molded rubber filter disc is designed to support and seal in place a filter crucible or a funnel in the neck of a filter flask. Inside diameter of the socket at top is 32 mm, and outside diameter of the disc is 76 mm. The bottom of the disc is flat, so that it seals tightly against the lip of the flask.
