Description
Two-necked flask, DURAN®, 1000 ml is a laboratory round flask with ground glass joints for multi-port reaction and distillation assemblies at litre scale. It offers a 1000 ml capacity and is equipped with a centre neck NS 29/32 together with an angled side neck NS 19/26, enabling concurrent use of condensers, dropping funnels, stoppers or temperature probes without opening the system. Manufactured from DURAN® glass by Lenz, the flask is intended for preparative chemistry, reflux work and routine jointed-glassware applications in research and teaching environments. The angled side arm helps keep connected apparatus clear of one another on the bench or inside a fume hood. Supplied as 1 pc(s) with a weight of 0,308 kg, it integrates into standard NS inventories and typical heating-mantle setups. Clearly stated joint sizes (centre 29/32, angled side 19/26) simplify selection, pairing and replacement wherever interchangeable ground-joint components are required for medium- to larger-scale liquid handling and synthesis.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Two-necked flask, DURAN®, 1000 ml, angled side neck 19/26, centre 29/32
What is this article?
Two-necked flask, DURAN®, 1000 ml, angled side neck 19/26, 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.
