Description
Erlenmeyer flask, 2000 ml, socket NS 45/40 is a large conical laboratory flask fabricated from borosilicate glass 3.3 for mixing, heating, storage and culture applications. It offers a nominal volume of 2 l, a diameter of 166 mm and a height of 280 mm, providing ample capacity together with a stable footprint and good swirling behaviour. The NS 45/40 ground joint socket enables reliable connection to condensers, stoppers or transfer adapters in standard laboratory assemblies. Made by manufacturer Rettberg, the vessel delivers the chemical durability and thermal resistance characteristic of borosilicate glass 3.3. A net weight of 0,520 kg indicates solid construction while remaining manageable for everyday use. Transparent walls allow easy observation of contents and reaction progress. This single-piece flask is intended for chemistry, life-science, pharmaceutical and quality-control laboratories performing media preparation, larger-scale titrations, incubations and general liquid handling. It fits seamlessly into glassware collections that utilise NS 45/40 joints and supports both routine and preparative workflows.

Questions about Erlenmeyer flask, 2000 ml, socket size 45/40
What is this article?
Erlenmeyer flask, 2000 ml, socket size 45/40 is the article on this page. Luminix Health distributes Rettberg 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.
