Description
The nitrogen round bottom flask with stopcock is a DURAN® laboratory glass vessel with a 100 ml capacity and an NS 14/23 ground joint. As a round-bottom flask fitted with a stopcock, it is intended for nitrogen-focused and general laboratory applications that benefit from a jointed glass body and stopcock-controlled access. The spherical base favours even thermal contact and efficient mixing when the flask is mounted in standard laboratory hardware. This DURAN® flask from manufacturer Lenz combines established laboratory glass quality with a practical stopcock for opening, closing, or linking the vessel to other apparatus. The NS 14/23 joint ensures compatibility with widely used ground-glass connectors, adapters, and reaction setups. Provided as one piece at 0,108 kg, the item sits within the category of round flasks and flasks with ground glass joints and offers a larger 100 ml working volume for laboratories that specify a nitrogen round-bottom flask with stopcock in the NS 14/23 format for preparative or routine experimental work.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen round bottom flask w. stopcock, DURAN®, 100 ml, NS 14/23, 1 unit(s)
What is this article?
Nitrogen round bottom flask w. stopcock, DURAN®, 100 ml, NS 14/23, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
