Description
Erlenmeyer flask DURAN® 50 ml narrow neck with NS 19/26 ground joint is a conical laboratory flask made from borosilicate glass 3.3. White graduations support clear volume orientation during preparation, dilution and mixing. The narrow-neck design combined with standard ground joint NS 19/26 allows secure connection to stoppers and complementary glassware. With a nominal volume of 50 ml (0,05 l) and a height of 85 mm, the flask is produced according to DIN 12 387 for consistent laboratory dimensions. Borosilicate glass 3.3 provides the thermal and chemical resistance expected in general chemistry, culture work and routine sample handling. Supplied in packs of 10 pieces from manufacturer Hirschmann, these DURAN® Erlenmeyer flasks suit everyday bench use where a reliable conical vessel with a defined joint is required. The conical body promotes efficient swirling while the graduated scale aids approximate volume checks without transferring liquid to a separate measuring cylinder, supporting efficient workflow in teaching and research laboratories.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about ERLENMEYER FLASK DURAN 50 ML, NARROW NECK WITH NS 19/26
What is this article?
ERLENMEYER FLASK DURAN 50 ML, NARROW NECK WITH NS 19/26 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.
