Description
Erlenmeyer flask DURAN® 300 ml wide neck with beaded rim is a conical laboratory flask fabricated from borosilicate glass 3.3 for chemical and biological applications. White graduations assist approximate volume assessment, while the wide neck and beaded rim facilitate filling, agitation, pouring and cleaning. The flask measures 156 mm in height, provides a 50 mm neck diameter and holds a nominal volume of 300 ml (0,3 l). Conforming to DIN 12 385, this DURAN® vessel combines thermal shock resistance with the chemical durability of borosilicate 3.3 glass. Supplied in packs of 10 pieces from manufacturer Hirschmann, the flasks support media preparation, titrations, culture handling and general laboratory sample work where a robust conical shape and convenient access are required. The beaded rim reinforces the mouth during repeated use, and the white graduation marks aid everyday workflows without replacing certified volumetric glassware. These wide-neck Erlenmeyer flasks are readily incorporated into standard laboratory procedures for mixing, gentle heating and temporary storage of solutions under controlled conditions.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about ERLENMEYER FLASK DURAN 300 ML, WIDE NECK WITH RIM
What is this article?
ERLENMEYER FLASK DURAN 300 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.
