Description
Erlenmeyer flask, narrow neck, Duran®, with graduation 250 ml is a conical laboratory vessel intended for mixing, heating, holding and approximate volume measurement of liquids in routine scientific work. Fabricated from borosilicate glass 3.3, the flask combines a narrow neck with permanent graduation markings that support quick visual estimation of contents during sample preparation and transfer. The classic conical body promotes efficient swirling while limiting splash-out, making the item suitable for media preparation, titrations, dissolution steps and general culture handling. Supplied as a single piece from manufacturer Hecht, this 250 ml Duran® flask integrates readily into chemistry, biology and pharmaceutical bench workflows where durable glassware with clear scale divisions is required. The narrow-neck geometry accepts common stoppers or closures to reduce evaporation and contamination risk during short-term storage or incubation. Borosilicate glass 3.3 construction provides the thermal and chemical resistance expected of standard laboratory flasks of this type. Ideal for teaching laboratories, quality-control benches and research groups that rely on graduated Erlenmeyer flasks for everyday experimental procedures.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, narrow neck, Duran®, with scale 250 ml
What is this article?
Erlenmeyer flasks, narrow 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.
