Description
Erlenmeyer flask with standard ground joint and graduation, without stopper, Boro 3.3 is a conical laboratory vessel fabricated from borosilicate glass 3.3 for consistent chemical resistance and thermal behaviour in everyday laboratory practice. This 250 ml model is equipped with a standard ground joint sleeve NS 24/29 and clear graduation marks, enabling approximate volume assessment and reliable connection to matching ground-joint components. White enamel inscription supports durable labelling under normal lab conditions. Built to DIN EN ISO 4797 and supplied without a stopper, the flask serves mixing, gentle heating, reagent preparation and sample transfer applications where a stable conical form is advantageous. The tapered body facilitates efficient swirling of liquids and suspensions, while the wide base enhances bench-top stability. Available in a pack of 6 pieces from manufacturer Hecht, these graduated Erlenmeyer flasks suit teaching laboratories, quality-control workflows and research benches that depend on standardised Boro 3.3 glassware. Jointed connectivity, graduation and sturdy construction combine to offer a reusable, practical solution for wet-chemistry tasks requiring both apparatus compatibility and visual volume guidance.

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.
