Description
Erlenmeyer flask 250 ml NS 24/29 is a graduated conical flask manufactured from borosilicate glass 3.3 for general laboratory use. The vessel features a standard ground joint NS 24/29, an outer diameter of 85 mm and a height of 140 mm, giving a stable footprint and compatibility with common stoppers and adapters. Clear glass construction allows easy observation of contents, colour changes and mixing behaviour during heating, swirling or storage. With a nominal volume of 0,25 l, the flask is well suited to culture work, titrations, sample preparation and intermediate reaction steps. Produced by manufacturer Witeg, the borosilicate 3.3 material provides the thermal and chemical resistance expected in routine laboratory glassware. Graduation markings support approximate volume assessment without transfer to a measuring cylinder. Supplied in packs of ten pieces, these flasks fit standard heating mantles, clamps and storage racks used in teaching, research and quality-control laboratories that require durable NS-joint Erlenmeyer vessels.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flask 250 ml ST 24/29
What is this article?
Erlenmeyer flask 250 ml ST 24/29 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.
