Description
Narrow neck Erlenmeyer flask, DURAN® is a large-capacity laboratory conical flask with graduation, offered in a 5000 ml size and designed in accordance with ISO 1773. The narrow-neck geometry supports controlled pouring, reduced evaporation during standing, and secure stopper or closure fit when samples or media must be held between process steps. Clear graduation markings allow approximate volume reading directly on the vessel wall, which is useful for preparation, dilution, and bulk handling workflows in research, quality control, and teaching laboratories. Supplied as a single piece with a stated weight of 1,500 kg, this flask suits benches and setups that require a robust, high-volume conical vessel rather than multiple smaller containers. The DURAN® Erlenmeyer design from manufacturer DWK Life Sciences is a familiar choice for general laboratory glassware ranges covering beakers and Erlenmeyer flasks. Use it where a graduated, ISO 1773-aligned narrow-neck conical flask of 5000 ml is specified for mixing, temporary storage, or transfer of liquids under routine laboratory conditions. Pack configuration is one unit per pack for straightforward stock and replacement planning.
This article belongs on Erlenmeyer flasks, in Beakers & flasks.

What is this article?
Narrow neck Erlenmeyer flask, DURAN®, graduation, 5000 ml, ISO 1773, 1 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
