Description
Erlenmeyer flask 200 ml NS 45/40 is a graduated conical laboratory flask made from clear borosilicate glass 3.3 and fitted with a standard ground joint NS 45/40. It provides a nominal volume of 0,2 l, an outer diameter of 79 mm and a height of 130 mm, making it well suited for mixing, heating, swirling and culture applications in chemical and biological laboratories. The clear glass body ensures good visibility of contents while the borosilicate glass 3.3 construction delivers the thermal and chemical durability expected in routine lab work. Graduations support approximate volume estimation during procedures. The wide NS 45/40 joint allows secure connection to condensers, stoppers or other ground-joint glassware. Supplied in packs of 10 pieces from manufacturer Witeg, this Erlenmeyer flask is a practical choice for research, analytical and teaching environments that require reliable conical flasks with large standard joints. Its standardised dimensions and robust material support efficient daily laboratory workflows involving liquids under controlled conditions.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flask 200 ml ST 45/40
What is this article?
Erlenmeyer flask 200 ml ST 45/40 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.
