Description
Erlenmeyer flask with standard ground joint NS 19/26, GLASSCO, 250 ml, 10 pcs is a multipack of conical laboratory flasks made from high-quality borosilicate glass LBG 3.3. Each flask is manufactured in accordance with ISO 4797 and combines a nominal volume of 250 ml with a standardised ground joint NS 19/26 for reliable coupling to stoppers, adapters and condensers. The conical shape aids thorough mixing by swirling and helps reduce spillage during heating or reagent addition. Borosilicate glass 3.3 delivers the chemical resistance and thermal durability expected in everyday laboratory practice. The pack has a net weight of 1,595 kg for ten pieces. These GLASSCO series vessels from manufacturer Labbox are well suited to general chemistry, titrations, culture applications and sample preparation in research, teaching and industrial laboratories. Clear walls support visual monitoring of reactions and media, while the NS 19/26 joint ensures compatibility with standard European ground-joint apparatus. The ten-piece pack supports efficient restocking of busy benches and shared glassware pools.

Questions about Flask, Erlenmeyer, mouth 19/26, GLASSCO, 250 ml, 10 pcs
What is this article?
Flask, Erlenmeyer, mouth 19/26, GLASSCO, 250 ml, 10 pcs 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.
