Description
Erlenmeyer flask with graduation, borosilicate glass 3.3, with NS glass stopper is a conical laboratory vessel intended for general wet-chemistry work at a nominal volume of 100 ml. The flask combines clear graduation marks for approximate volume orientation with a ground joint sleeve NS24/29 and a matching NS glass stopper, allowing secure closure during mixing, standing, or short-term storage of solutions and reagents. Borosilicate glass 3.3 provides the thermal and chemical resistance expected in everyday laboratory practice, supporting heating, cooling, and contact with common solvents under standard bench conditions. The conical Erlenmeyer geometry promotes efficient swirling and reduces splash risk compared with cylindrical vessels, which is useful for sample preparation, dissolution steps, and teaching demonstrations. This graduated flask with NS glass stopper from manufacturer Hecht is offered in a practical multipack of 10 pieces, suited to research groups, teaching laboratories, and quality-control benches that require interchangeable conical flasks with standardized ground joints. The NS24/29 joint ensures compatibility with corresponding glassware accessories while the integrated stopper keeps the working volume protected between handling steps.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Flasks, erlenmeyer, (conical) narrow neck with socket, with glass stopper, Boro
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.
