This article is part of Erlenmeyer flasks, in Beakers & flasks.
Permanent graduation markings support approximate volume estimation during media preparation, solution handling, and routine culture or chemistry workflows. Borosilicate glass 3.3 delivers the chemical durability and thermal resistance expected of everyday laboratory glassware for heating, cooling, and general wet-lab use. Supplied from manufacturer Witeg in packs of 10 pieces, each flask has a net weight of 0,122 kg. The wide-neck geometry eases spatula work and stopper placement, while the rim aids secure handling. This DURAN® Erlenmeyer flask suits teaching, research, and quality-control laboratories that require reliable conical vessels for mixing, temporary storage of liquids, and standard sample preparation.

Questions about Erlenmeyer flask 250 ml wide neck with rim
What is this article?
Erlenmeyer flask 250 ml wide neck with rim is the article on this page. Luminix Health distributes Witeg 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.
