Description
Nitrogen round-bottom flask, DURAN® is a laboratory glass vessel for medium-scale reactions and sample work under a protective nitrogen atmosphere. It offers a round-bottom body, a ground joint NS 29/32 and a 2,5 mm borehole that enables controlled gas inlet or outlet. Nominal capacity is 100 ml and overall height is 105 mm, dimensions that balance working volume with a manageable footprint on the bench or in a fume hood. Supplied as 1 pc(s) and weighing 0,217 kg, the DURAN® flask integrates readily with standard laboratory stands, clamps and heating equipment. This nitrogen round-bottom flask from manufacturer Lenz supports inert-gas blanketing, exclusion of air and moisture, and typical operations such as reactions, distillations and handling of air-sensitive intermediates. The NS 29/32 joint ensures broad compatibility with stoppers, adapters and condensers used throughout research and teaching laboratories. Round-bottom geometry promotes uniform mixing and heat distribution, while the dedicated borehole simplifies reproducible nitrogen connection in everyday protective-atmosphere glassware assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen round-bottom flask, DURAN®, NS 29/32, H 105mm, borehole 2.5mm, 100ml
What is this article?
Nitrogen round-bottom flask, DURAN®, NS 29/32, H 105mm, borehole 2.5mm, 100ml 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.
