Description
Erlenmeyer flask with standard ground joint NS 19/26, GLASSCO, 250 ml is a conical laboratory flask made from high-quality borosilicate glass LBG 3.3. Produced in accordance with ISO 4797, it provides a nominal volume of 250 ml and a standardised ground joint NS 19/26 for secure connection to stoppers, adapters and condensers. The conical body supports efficient swirling and mixing while limiting splash-out during heating or reagent addition. Borosilicate glass 3.3 offers strong chemical resistance and good thermal-shock performance for routine laboratory use. Net weight is 0,159 kg for the single unit. This GLASSCO series flask from manufacturer Labbox suits general chemistry, titrations, culture work and sample preparation in research, teaching and quality-control laboratories. Clear walls allow easy observation of contents and colour changes, and the NS 19/26 joint maintains compatibility with common European ground-joint systems. Supplied as one piece for flexible stocking and straightforward replacement in daily workflows.

Questions about Flask, Erlenmeyer, mouth 19/26, GLASSCO, 250 ml
What is this article?
Flask, Erlenmeyer, mouth 19/26, GLASSCO, 250 ml is the article on this page. Luminix Health distributes Labbox 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.
