Description
Flat-bottom flask 2000 ml NS 45/40 is a clear laboratory flask manufactured from borosilicate glass 3.3. It provides a nominal volume of 2 l, an outer diameter of 166 mm and a height of 245 mm, together with a medium neck finished to the standardised NS 45/40 ground joint. The broad flat base offers stable support on hotplates, stirrers or benches during heating and mixing, while the large joint enables secure coupling to condensers, adapters and distillation assemblies. Produced by Witeg, the flask utilises the proven thermal-shock resistance and chemical durability of borosilicate glass 3.3, making it appropriate for larger-volume boiling, reflux, extraction and sample-preparation tasks. Clear glass construction allows continuous visual monitoring of contents and reaction progress. Supplied in packs of 10 pieces, these flasks deliver consistent dimensions and reliable joint geometry for research, process-development and quality-control laboratories that require robust standing flasks for everyday wet-chemistry applications.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Flat bottom flask 2000 ml ST 45/40
What is this article?
Flat bottom flask 2000 ml ST 45/40 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
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.
