Description
Three-necked round-bottom flask, DURAN® is a laboratory glass vessel with a nominal capacity of 6000 ml, fitted with side necks of NS 14/23 and a centre neck of NS 29/32. The round-bottom geometry supports even heating and mixing, while the three ground-glass joints enable simultaneous mounting of smaller side accessories together with a standard central condenser, stirrer guide or thermometer adapter. Delivered as 1 pc(s) and weighing 1,650 kg, this large-volume flask is aimed at preparative and process-oriented work where compact NS 14/23 side ports are preferred alongside an NS 29/32 centre joint. DURAN® glass construction from manufacturer Lenz provides a conventional multi-neck layout that integrates with common European ground-joint glassware. The vessel is appropriate for research, teaching and development laboratories that require a 6000 ml three-neck round-bottom flask for controlled reagent addition, reflux, sampling or gas introduction within one assembly.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 6000 ml, side necks 14/23, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 6000 ml, side necks 14/23, centre 29/32 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.
