Description
Erlenmeyer flask DURAN® 25 ml is a narrow-neck conical flask made from borosilicate glass 3.3, fitted with a ground joint NS 14/23 for secure connection to compatible glassware. Nominal volume is 25 ml, overall height is 70 mm, and the flask carries white graduation markings for convenient volume orientation during laboratory work. Construction follows DIN 12 387, supporting standardised use in preparation, mixing, culture-related and general chemistry applications. The narrow-neck design limits evaporation and splash compared with wide-neck forms, while the DURAN® borosilicate 3.3 material provides the thermal and chemical resistance expected of this glass type in everyday lab practice. Offered in packs of 10 pieces from manufacturer Hirschmann, the flask suits teaching, research and routine laboratory setups that require a compact 25 ml Erlenmeyer with a defined NS 14/23 joint. White graduation aids quick visual checks without replacing volumetric glassware where higher accuracy is mandatory. A practical choice for heating, swirling and jointed assemblies within the 25 ml working range.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about ERLENMEYER FLASK DURAN 25 ML, NARROW NECK WITH NS 14/23
What is this article?
ERLENMEYER FLASK DURAN 25 ML, NARROW NECK WITH NS 14/23 is the article on this page. Luminix Health distributes Hirschmann 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.
