Description
Three-necked round-bottom flask, DURAN® is a multi-neck laboratory vessel for reaction, reflux and distillation work that requires several simultaneous ground-joint connections. This 6000 ml flask provides two side necks with 29/32 joints and a centre neck of 29/32, so condensers, dropping funnels, stirrer guides or temperature probes can be fitted in a compact geometry. The round-bottom form supports uniform heating and mixing in larger preparative batches, while DURAN® glass delivers the chemical and thermal resistance expected in synthetic and process laboratories. Supplied as 1 pc and weighing 1,436 kg, the flask is sized for scale-up experiments, pilot preparations and multi-component setups where standard NS joints are preferred. From manufacturer Lenz, it belongs to the established range of round flasks with ground glass joints used across organic synthesis, solvent handling and general laboratory glassware assemblies. The three-neck layout keeps apparatus organised on the bench or in a heating mantle and simplifies addition, sampling and vapour take-off without dismantling the main joint. Choose this configuration when equal centre and side joint sizes streamline inventory and connector choice for 6000 ml work.
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 29/32, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 6000 ml, side necks 29/32, 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.
