Description
Erlenmeyer flask DURAN® 250 ml wide neck with beaded rim is a conical laboratory flask produced from borosilicate glass 3.3 for routine preparation and handling of liquids. White graduations allow approximate volume checks, and the wide neck with beaded rim simplifies charging, mixing, decanting and cleaning. Height is 140 mm, neck diameter 50 mm and nominal volume 250 ml (0,25 l). Built according to DIN 12 385, the DURAN® design delivers the thermal and chemical resistance characteristic of borosilicate 3.3 glassware. Offered in packs of 10 pieces from manufacturer Hirschmann, these flasks are well suited to media make-up, titrations, culture work and general sample processing where a stable conical body and easy access are advantageous. The beaded rim strengthens the opening for frequent use, while the white scale supports day-to-day laboratory tasks without substituting precision volumetric ware. Wide-neck Erlenmeyer flasks of this type integrate smoothly into standard lab benches for swirling, gentle heating and short-term solution holding under controlled conditions.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

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