Flask Boiling with Joint

Flask Boiling with Joint

Round-bottom flasks with Joint connector (also called Boiling Flasks) are types of flasks having spherical bottoms used in laboratory. They are made of heat-resistant borosilicate glass. One neck with a rimmed opening at the tip. Available from 250ml to 5 000ml with  other capacity available on request.

Because of the round bottom, cork rings are needed to keep the round bottom flasks upright. When in use, round-bottom flasks are commonly held at the neck by clamps on a stand.
