Description
Erlenmeyer flask with graduation, borosilicate glass 3.3, with NS glass stopper is a 300 ml conical laboratory flask intended for everyday mixing, preparation and handling of liquids. Graduated markings on the body support approximate volume assessment, while the NS glass stopper closes the ground neck for secure use on the bench. The joint size is NS 29/32, matching widely used laboratory ground-joint systems. Constructed from borosilicate glass 3.3, the flask provides clear visibility of contents and the mechanical form expected of standard Erlenmeyer glassware. This graduated stoppered flask from manufacturer Hecht is offered as one piece and suits research, teaching and routine laboratory environments. The conical profile with flat base aids swirling and stable standing; the narrower neck with NS stopper helps reduce splash and evaporative loss during work. Graduation supports quick visual checks alongside other measuring tools. With NS 29/32 geometry and borosilicate glass 3.3 construction, the 300 ml flask integrates smoothly into existing glassware sets for solution preparation, media work and general sample handling.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, borosilicate glass 3.3, with interchangeable glass stopper
What is this article?
Erlenmeyer flasks, borosilicate glass 3.3, with interchangeable glass stopper 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.
