Questions about Flat bottom flasks, borosilicate glass 3.3, with standard ground joint, without
What is this article?
Flat bottom flasks, borosilicate glass 3.3, with standard ground joint, without is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
