Description
Erlenmeyer flask 250 ml with standard ground joint NS 29/32 is a conical laboratory flask manufactured from borosilicate glass 3.3. Produced in accordance with DIN 12 387, it combines a durable glass body with a standardised NS 29/32 ground joint for reliable connection to compatible stoppers, condensers and other jointed apparatus. White graduation markings on the wall support approximate volume orientation during routine preparation, mixing and transfer work. The flask is supplied without a stopper, so laboratories can fit the closure that best matches their process. With a nominal volume of 0,25 l, this format is widely used for sample preparation, media handling, heating under controlled conditions and general wet-chemistry tasks in research, quality control and teaching laboratories. Borosilicate glass 3.3 offers the thermal and chemical resistance expected for everyday laboratory use with aqueous and many organic media. Packed in cartons of 10 pieces from manufacturer Marienfeld, the unit quantity suits bench stocking and shared laboratory stores while keeping the standardised joint geometry consistent across the set.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks 250 ml with ground joint NS 29/32
What is this article?
Erlenmeyer flasks 250 ml with ground joint NS 29/32 is the article on this page. Luminix Health distributes Marienfeld 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.
