Description
Three-necked round-bottom flask, DURAN® is a multi-neck laboratory vessel for chemical synthesis, reflux and distillation-style work needing concurrent connections. This 1000 ml flask features a centre ground joint of 29/32 and two side necks of 19/26, allowing condensers, dropping funnels, thermometers or stirrer assemblies to be attached on standard joints. The round-bottom geometry aids even heating with mantles or baths and supports efficient agitation of mixtures. Manufactured as DURAN® glassware by Lenz, the flask comes as a single piece weighing 0,330 kg. Three-necked round-bottom flasks with specified joint sizes are widely used in organic and inorganic laboratories, preparative chemistry and educational practicals that demand controlled reagent addition and ongoing observation. Compatible joint dimensions ease integration with everyday adapters, stoppers and ancillary glass components. Clear labelling of centre and side necks helps match the flask to multi-port apparatus. With a unit quantity of 1 pc, it is suited to individual bench setup or replacement within existing glassware collections used for closed reaction systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 1000 ml, side necks 19/26, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 1000 ml, side necks 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.
