Description
Three-necked round-bottom flask, DURAN® is a multi-neck laboratory flask intended for reactions, distillations and process steps that require several ground-joint connections at the same time. With a nominal capacity of 500 ml, this model is equipped with side necks sized 19/26 and a centre neck sized 24/29, so condensers, addition funnels and temperature probes can be mounted together. The round-bottom profile supports uniform heating with mantles or baths and is compatible with common laboratory supports. Manufactured in DURAN® glass by Lenz, the flask serves synthetic, preparative and teaching applications in the category of round flasks and flasks with ground glass joints. Offered as 1 pc and weighing 0,250 kg, it is appropriate for larger bench-scale work and scale-up trials that still need a compact multi-port vessel. Joint sizing follows familiar laboratory standards, easing use alongside existing DURAN® and compatible glassware. Three-necked round-bottom flasks are selected when addition, reflux and monitoring must be combined in one defined working 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®, 500 ml, side necks 19/26, centre 24/29
What is this article?
Three-necked round-bottom flask, DURAN®, 500 ml, side necks 19/26, centre 24/29 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.
