Description
Erlenmeyer flask, wide neck, Duran®, with graduation 250 ml is a conical laboratory flask for mixing, heating and general liquid handling. Constructed from borosilicate glass 3.3, it delivers the thermal shock resistance and chemical durability associated with this material in standard laboratory practice. The wide neck eases filling, addition of solids or liquids, cleaning and access with spatulas or pipettes, while permanent graduation markings allow approximate volume assessment during preparations. Available as 1 pc from manufacturer Hecht, the vessel is appropriate for culture work, media and buffer preparation, dissolution steps and routine analytical workflows that benefit from a stable conical profile. Duran® quality glass maintains clarity for observation of suspensions, precipitates and colour reactions. The 250 ml capacity covers common mid-range volumes in research, teaching and quality-control settings. The conical shape concentrates contents at the base, supporting efficient swirling and stirring with reduced spill risk compared with straight-walled containers.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, wide neck, Duran®, with scale 250 ml
What is this article?
Erlenmeyer flasks, wide neck, Duran®, with scale 250 ml is the article on this page. Luminix Health distributes Hecht 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.
