Description
Narrow neck Erlenmeyer flasks, DURAN® are graduated conical laboratory vessels with a 500 ml working capacity, produced in accordance with ISO 1773. The classic Erlenmeyer profile combines a stable base with sloping walls and a narrow neck, supporting controlled swirling, mixing and temporary holding of liquids during routine wet-chemistry work. Permanent graduation markings help the user estimate fill levels for sample preparation, media handling and general solution transfer. Supplied as a pack of 10 units from manufacturer DWK Life Sciences, the set has a stated pack weight of 2,100 kg and is intended for everyday use on analytical, teaching and quality-control benches. DURAN® glassware is a familiar choice wherever dimensional consistency and repeated laboratory handling of conical flasks are required. The narrow-neck format limits splash and evaporative loss relative to wide-neck designs while remaining compatible with common laboratory stoppers and closures. ISO 1773 alignment supports interchangeability within established glassware collections. These 500 ml flasks suit titration support steps, buffer and reagent preparation, and general liquid handling workflows that rely on graduated Erlenmeyer vessels.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Narrow neck Erlenmeyer flasks, DURAN®, graduation, 500 ml, ISO 1773, 10 unit(s)
What is this article?
Narrow neck Erlenmeyer flasks, DURAN®, graduation, 500 ml, ISO 1773, 10 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.
