Questions about Erlenmeyer flask 500 ml ST 45/40 Economy
What is this article?
Erlenmeyer flask 500 ml ST 45/40 Economy is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
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.
