Description
Three-necked round-bottom flask, DURAN® is a laboratory glass vessel configured for reaction and process work that requires several ground-joint connections at once. This 100 ml flask provides two side necks of size 19/26 together with a centre neck of size 29/32, so condensers, dropping funnels, stirrer guides or temperature sensors can be fitted in parallel. The round-bottom profile supports even heating and is commonly used with heating mantles, oil baths and standard laboratory supports. Produced in DURAN® glass by manufacturer Lenz, the flask is intended for everyday synthetic, preparative and teaching applications within the category of round flasks and flasks with ground glass joints. It is offered as 1 pc and weighs 0,110 kg, which suits bench-scale experiments and method optimisation where a compact multi-neck vessel is preferred. Joint dimensions follow common laboratory standards, helping the flask integrate into existing DURAN® and compatible glassware assemblies. Laboratories select three-necked round-bottom designs when simultaneous addition, reflux and monitoring must be combined in a single vessel of defined volume.
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 19/26, centre 29/32
What is this article?
Three-necked round-bottom flask, DURAN®, 100 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 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.
