Description
Round flask DURAN® transparent glass, 1000 ml, NS 24/29 is a one-litre round-bottom flask in transparent DURAN® glass fitted with a standard ground joint NS 24/29. With a 1000 ml capacity and a unit weight of 0,285 kg, it is intended for larger laboratory distillations, solvent recovery, and bulk sample preparation where visual control remains important. The flask is supplied as 1 pc and aligns with distillation and Soxhlet appliances, environmental analysis, and sampling or sample-preparation applications that use NS 24/29 connections. Its spherical body aids even heating and thorough mixing, while the transparent wall allows operators to follow boiling behaviour, phase boundaries, and colour development throughout a run. Manufactured by Lenz, this DURAN® transparent glass round flask serves research, teaching, and quality-control laboratories that need a robust 1000 ml vessel compatible with common condensers and adapters. Standardising on the NS 24/29 joint simplifies apparatus assembly for repeated distillation, extraction, and work-up sequences at the one-litre scale.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 1000 ml, NS 24/29, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 1000 ml, NS 24/29, 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.
