Description
Erlenmeyer flask with standard ground joint and graduation, without stopper, is produced from borosilicate glass Boro 3.3 with white inscription and conforms to DIN EN ISO 4797. The conical vessel has a nominal volume of 25 ml and a socket ground joint NS 14/23 for connection to stoppers, adapters or other jointed laboratory glassware. Graduations support approximate volume reading during mixing, titration preparation and sample handling. The wide base and sloping walls aid swirling and reduce splash-out compared with cylindrical flasks. Supplied without a stopper, the flask leaves the choice of closure free for the intended method. White inscription provides durable marking for identification in multi-sample workflows. Available as a pack of 10 pieces from manufacturer Hecht, this graduated Erlenmeyer flask is suited to routine wet chemistry, media preparation and teaching laboratories that rely on chemical resistance and thermal stability of Boro 3.3 glass. The NS 14/23 joint ensures compatibility with standard European small-joint assemblies for compact reaction and storage setups.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Flasks, erlenmeyer, (conical) narrow neck with socket, Boro 3.3, DIN EN ISO
What is this article?
Flasks, erlenmeyer, (conical) narrow neck with socket, Boro 3.3, DIN EN ISO is the article on this page. Luminix Health distributes Hecht 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.
