Description
Erlenmeyer flask DURAN® 250 ml narrow neck with beaded rim is a conical laboratory flask made of borosilicate glass 3.3. It carries white graduations for easy volume reading and combines a narrow neck with a beaded rim for secure handling and reliable stopper seating. Nominal volume is 250 ml, height 140 mm and neck diameter 34 mm, conforming to DIN 12 380 for standardised laboratory glassware geometry.
This article is part of Erlenmeyer flasks, in Beakers & flasks.
The conical form enables efficient mixing and swirling of liquids, while borosilicate glass 3.3 supplies the thermal and chemical durability expected in daily laboratory heating, dissolving and sample-preparation steps. Pack size is 10 pc(s). These DURAN® flasks from manufacturer Hirschmann are appropriate for analytical chemistry, media preparation, culture applications and general research use where a robust 250 ml narrow-neck Erlenmeyer is required. The beaded rim strengthens the flask mouth and aids safe gripping during transfer or titration, and the white graduation markings support quick visual estimation of contents throughout the workflow.

Questions about ERLENMEYER FLASK DURAN 250 ML, NARROW NECK WITH RIM
What is this article?
ERLENMEYER FLASK DURAN 250 ML, NARROW NECK WITH RIM 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.
