Description
Erlenmeyer flask 25 ml NS 19/26 is a graduated conical laboratory flask manufactured from clear borosilicate glass 3.3 for general chemical and analytical work. The vessel offers a nominal volume of 25 ml with a standard ground joint NS 19/26, an outer diameter of 42 mm and a height of 70 mm, providing a stable footprint and convenient handling on the bench. Borosilicate glass 3.3 delivers the thermal shock resistance and chemical durability expected in routine laboratory use, while the clear wall and graduation markings support straightforward volume estimation and visual observation of contents. The NS 19/26 joint allows secure connection to stoppers, condensers or other ground-joint glassware. Supplied by manufacturer Witeg in practical multi-packs, this Erlenmeyer flask is suitable for sample preparation, mixing, heating under mild conditions, culture work and general wet-chemistry applications where a compact conical flask with a defined joint size is required. The combination of precise geometry, graduated scale and robust glass composition makes it a reliable everyday item for research, quality-control and teaching laboratories.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flask 25 ml ST 19/26
What is this article?
Erlenmeyer flask 25 ml ST 19/26 is the article on this page. Luminix Health distributes Witeg 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.
