Description
Erlenmeyer flask, narrow neck, Duran®, with graduation 25 ml is a laboratory glass vessel manufactured from borosilicate glass 3.3. The flask features a narrow neck and permanent graduation markings for the nominal 25 ml volume. Duran® glass of borosilicate 3.3 composition provides the material basis for this conical flask, combining thermal and chemical resistance typical of the glass type. The narrow-neck design and graduated scale support controlled mixing, heating or storage of liquids in analytical and preparative work. This Erlenmeyer flask is supplied by manufacturer Hecht as a single piece. The 25 ml capacity with graduation allows volume estimation directly on the vessel wall. Borosilicate glass 3.3 remains the sole material stated, ensuring the description matches the available scientific specifications exactly. Suitable for general laboratory use wherever small-volume Erlenmeyer flasks with narrow necks are required, the item integrates into standard glassware sets for chemistry, biology or quality-control applications without further modification.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, narrow neck, Duran®, with scale 25 ml
What is this article?
Erlenmeyer flasks, narrow neck, Duran®, with scale 25 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.
