Description
Erlenmeyer flask with standard ground joint and graduation, without stopper, Boro 3.3 is a conical laboratory flask for mixing, heating and short-term holding of liquids. This 50 ml unit provides a socket joint NS 24/29 for secure coupling to standard ground-joint apparatus and features a durable white inscription that remains legible under routine bench conditions. Produced from borosilicate glass 3.3 to DIN EN ISO 4797, the flask delivers the thermal and chemical resistance associated with everyday laboratory glassware, while the graduated conical form supports approximate volume checks during swirling and sample preparation. Supplied without a stopper, it is suited to open-neck workflows or use with separately selected closures. Packs of 10 pieces from manufacturer Hecht serve teaching laboratories, quality-control benches and research groups standardised on interchangeable NS joints. The classic Erlenmeyer geometry promotes efficient mixing with lower splash risk, making this flask a practical option for titrations, reagent preparation and general preparative work requiring reliable Boro 3.3 glassware.
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.
