Description
Erlenmeyer flask with graduation, borosilicate glass 3.3, with NS glass stopper is a small conical laboratory flask designed for mixing, dissolving, gentle heating and temporary storage of limited liquid volumes. It provides a nominal volume of 50 ml together with a socket ground joint NS 14/23 and a matching NS glass stopper for dependable sealing. Graduations on the vessel wall allow quick visual volume checks during sample preparation, teaching experiments and routine analytical work. Borosilicate glass 3.3 offers high resistance to thermal shock and chemical attack, supporting repeated use with common laboratory reagents. The conical geometry promotes effective swirling and mixing, while the smaller NS 14/23 joint suits compact setups and lighter glassware trains. Supplied complete with stopper from manufacturer Hecht, the flask is ready for immediate integration into wet-chemistry workflows. Pack size is 10 pieces, ideal for equipping student laboratories, method-development benches and quality-control stations that standardise on 50 ml graduated Erlenmeyer flasks with NS 14/23 connections.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

What is this article?
Flasks, erlenmeyer, (conical) narrow neck with socket, with glass stopper, Boro is the article on this page. Luminix Health distributes Hecht 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.
