Description
Round flask DURAN®, transparent glass, 50 ml, NS 14/23 is a laboratory round flask intended for distillation, sample preparation, and jointed glass assemblies. Clear DURAN® glass offers thermal and chemical robustness together with straightforward visual inspection of the contents during heating, reflux, or solvent handling. The 50 ml capacity is well matched to medium-small reaction and work-up volumes, while the NS 14/23 ground joint ensures standardized coupling to condensers, still heads, and other NS 14/23 components. At a weight of 0,033 kg and packed as 1 pc, the flask is convenient for everyday use in environmental analysis, sampling and sample-preparation trains, and Soxhlet or distillation apparatus. This round flask from manufacturer Lenz fits modular European ground-joint systems used in research, teaching, and quality-control laboratories. Transparent DURAN® construction supports process monitoring, and the NS 14/23 joint maintains interchangeability across common laboratory glassware setups without specialized adapters for standard configurations.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 50 ml, NS 14/23, 1 pc
What is this article?
Round flasks,DURAN®, transparent glass, 50 ml, NS 14/23, 1 pc 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.
