Description
Three-necked round-bottom flask, DURAN® is specified at 2000 ml with side necks 29/32 and a centre neck 45/40. The round-bottom vessel and three ground-glass joints are intended for laboratory assemblies that need larger joint sizes on both the side and centre ports. Side necks 29/32 accommodate correspondingly sized accessories, while the wide centre joint 45/40 supports substantial central fittings such as large condensers or specialised adapters. Packaged as 1 pc and weighing 0,580 kg, this DURAN® flask from manufacturer Lenz belongs to the family of round flasks with ground glass joints used in synthesis and process-oriented lab work. The three-neck arrangement enables multi-component setups without continuous opening of the reaction space. Capacity together with the 29/32 and 45/40 neck combination defines this particular 2000 ml variant for clear selection against other three-necked round-bottom flasks. It suits workflows that specifically call for larger ground joints on a 2000 ml DURAN® three-neck flask.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 2000 ml, side necks 29/32, centre 45/40
What is this article?
Three-necked round-bottom flask, DURAN®, 2000 ml, side necks 29/32, centre 45/40 is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
