Description
Erlenmeyer flask 500 ml NS 45/40 is a graduated conical laboratory flask produced from borosilicate glass 3.3 in clear glass quality. Featuring a nominal volume of 500 ml and a standard ground joint NS 45/40, it enables secure, leak-resistant connections to stoppers, adapters, condensers and other ground-joint glassware used in chemical, biological and analytical laboratories. The flask measures 105 mm in outer diameter and 170 mm in height, offering a stable footprint and convenient handling for larger working volumes. Clear graduation marks allow approximate volume reading during media preparation, reagent dilution, titrations and culture applications. Supplied in packs of 10 pieces from manufacturer Witeg, it is well suited to stocking research groups, teaching laboratories and quality-control departments. Borosilicate glass 3.3 provides the thermal and chemical resistance expected of standard laboratory glassware. The classic Erlenmeyer geometry supports efficient swirling and mixing while helping to minimise splash and evaporation compared with cylindrical vessels. Ideal for culture work, sample preparation, solvent handling and routine procedures requiring a durable 500 ml Erlenmeyer flask with a large NS 45/40 joint.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flask 500 ml ST 45/40
What is this article?
Erlenmeyer flask 500 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.
