Description
Erlenmeyer flask with standard ground joint and graduation, without stopper, Boro 3.3 is a conical laboratory flask produced from borosilicate glass 3.3 to deliver reliable chemical durability and thermal stability for daily laboratory operations. This 250 ml version features a standard ground joint sleeve NS 19/26 and permanent graduation markings that assist approximate volumetric work and secure attachment to compatible jointed apparatus. White enamel inscription ensures lasting identification during repeated use. Conforming to DIN EN ISO 4797 and delivered without a stopper, the flask is suitable for mixing, moderate heating, titration setup and general sample handling. Its conical geometry promotes effective swirling while the broad base improves standing stability on the bench. Supplied in a pack of 6 pieces from manufacturer Hecht, these graduated Erlenmeyer flasks integrate readily into educational labs, QC environments and research settings that specify standardised Boro 3.3 glassware. Ground joint connectivity, clear graduation and robust construction together make the vessel a practical choice for procedures needing both apparatus coupling and visual volume orientation.

Questions about Flasks, erlenmeyer, (conical) narrow neck with socket, Boro 3.3, DIN EN ISO
What is this article?
Flasks, erlenmeyer, (conical) narrow neck with socket, Boro 3.3, DIN EN ISO 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.
