Description
Round flask DURAN®, transparent glass, 50 ml, NS 29/32 is a jointed laboratory flask for distillation, sample preparation, and related vacuum or atmospheric glassware trains. Produced from clear DURAN® glass, it provides chemical durability and unobstructed observation of liquids and suspensions during heating, cooling, or solvent exchange. The 50 ml working volume suits small- to mid-scale preparations, while the larger NS 29/32 ground joint connects directly to condensers, adapters, and apparatus built around the NS 29/32 standard. Weighing 0,060 kg and supplied as 1 pc, the flask is suited to routine bench work in environmental analysis, sampling workflows, and distillation or Soxhlet assemblies. This round flask from manufacturer Lenz integrates into modular European joint systems where a wider neck and NS 29/32 compatibility are preferred. Transparent DURAN® glass aids visual control of the process, and the standardized joint supports reliable, interchangeable setups in research, teaching, and analytical laboratories without nonstandard fittings for typical configurations.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 50 ml, NS 29/32, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 50 ml, NS 29/32, 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.
