Description
Round flask, DURAN®, transparent glass is a 3000 ml laboratory round-bottom flask with an NS 29/32 ground joint for distillation, Soxhlet, and related sample-preparation assemblies. The transparent DURAN® glass body allows visual monitoring of contents during heating, reflux, or solvent work common in environmental analysis and general organic laboratory practice. A single unit is supplied, with a weight of 0,696 kg, suitable as a dedicated large-volume flask in distillation trains or sampling setups that require an NS 29/32 connection. Manufactured by Lenz, this round flask integrates with standard ground-joint glassware used for distillation and Soxhlet appliances. The 3000 ml capacity supports larger batch volumes when preparing or processing samples, while the clear glass aids observation of boiling behaviour and liquid level. Use it where a transparent DURAN® round flask with NS 29/32 is specified for laboratory distillation and sample-preparation workflows.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 3000 ml, NS 29/32, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 3000 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.
