Description
Erlenmeyer flask with standard ground joint and graduation, without stopper, Boro 3.3 is a conical borosilicate glass 3.3 vessel intended for reliable laboratory mixing, heating and intermediate storage of liquids. This variant provides a nominal volume of 300 ml and a sleeve ground joint NS 29/32 for direct coupling to condensers, dropping funnels and other NS apparatus. Delivered without a stopper, it features white inscription and graduation markings that aid volume estimation and flask identification on the bench. The design follows DIN EN ISO 4797, supporting interchangeability with matching ground-joint glassware. Boro 3.3 construction gives the thermal shock resistance and chemical durability expected in routine organic and inorganic work. Available in a pack of 6 pieces from manufacturer Hecht, the flasks are convenient for equipping teaching laboratories, method-development benches or multi-user analytical suites. The wide base improves standing stability while the conical neck limits spillage during swirling or degassing. Typical applications include sample preparation, reflux and distillation setups, titrations and general wet-chemistry procedures that call for a graduated Erlenmeyer with a standardised NS 29/32 joint.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

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.
