Description
DURAN® Erlenmeyer flask with standard ground joint NS 45/40 is a 250 ml conical laboratory flask manufactured from borosilicate glass 3.3. Its generous base area makes the vessel suitable for preparing solutions and for storage on the laboratory bench. The additional standard ground joint allows a tight seal of the flask, which is useful when contents must remain closed during handling or short-term holding. A clearly legible graduated scale with graduation marks, printed as a fired-on and permanently durable white image, enables straightforward measurement of liquid volumes. The conical shape supports efficient mixing of multiple components. Laboratory uses include mixing several reagents, diluting solutions, measuring liquid quantities and heating. This flask from manufacturer Duran/DWK Life Sciences is part of the DURAN® range and utilises the established chemical resistance and thermal behaviour of borosilicate glass 3.3. Supplied as one piece with nominal volume 250 ml and joint size NS 45/40, it provides a practical, closable vessel for solution work, volumetric checks and general wet-chemistry tasks in research, quality control and teaching environments. Note that the 250 ml size with NS 45/40 is indicated as not according to DIN ISO.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about DURAN® Erlenmeyer Flask with standard ground joint
What is this article?
DURAN® Erlenmeyer Flask with standard ground joint is the article on this page. Luminix Health distributes DWK Life Sciences 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.
