Description
Round flasks in DURAN® transparent glass with a 2000 ml working volume and NS 29/32 standard ground joint support distillation, Soxhlet extraction and sample preparation in environmental and general laboratory workflows. The spherical body promotes even heating and efficient mixing of liquids under reflux or reduced pressure, while the clear borosilicate glass allows continuous visual monitoring of the contents. A precision-ground NS 29/32 neck ensures reliable, leak-resistant connections to condensers, adapters and other jointed glassware. Supplied as a single piece weighing 0,55 kg, the flask is suited to routine preparative work where chemical resistance and thermal stability matter. These vessels from manufacturer Lenz fit standard heating mantles, oil baths and clamps used in distillation trains and sample-concentration setups. Transparent DURAN® construction helps operators track colour changes, boiling behaviour and phase separations without interrupting the process. Ideal for analytical and preparative laboratories that require robust round-bottom flasks with defined joint geometry for reproducible assembly of multi-piece glass apparatus.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 2000 ml, NS 29/32, 1 pc
What is this article?
Round flasks,DURAN®, transparent glass, 2000 ml, NS 29/32, 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.
