Description
Three-necked round-bottom flask, DURAN®, 100 ml is a multi-neck laboratory vessel intended for reaction and process assemblies that demand three full-size ground-glass ports. Centre and side necks are all NS 29/32, providing uniform large-bore connections for condensers, stirrer guides, dropping funnels or gas spargers within a single closed system. The 100 ml round-bottom form promotes uniform heat distribution and effective mixing during reflux, synthesis and controlled reagent addition. DURAN® glass delivers the joint precision and mechanical robustness expected of standard laboratory multi-neck flasks. Identical NS 29/32 joints on all three necks simplify inventory management and allow interchangeable use of larger accessories without reducing adapters. Offered as one piece weighing 0,137 kg, the flask mounts readily in common heating and stirring setups. Produced by manufacturer Lenz, this three-necked DURAN® round-bottom flask supports modular apparatus design in research, scale-up and educational laboratories. Explicit joint sizing ensures straightforward matching to existing NS 29/32 stoppers, condensers and transfer components.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, DURAN®, 100 ml, side necks 29/32, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 100 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.
