Description
Three-necked round-bottom flask, DURAN® is a multi-neck laboratory vessel designed for synthesis and preparative operations that need larger joint openings alongside dual side access. This 1000 ml flask provides a centre ground joint of 45/40 with two side necks of 29/32, so wide-neck accessories, condensers, addition funnels or stirrer guides can be mounted securely. The round-bottom form supports uniform heating under mantles or baths and promotes effective mixing of reaction mixtures. Supplied from manufacturer Lenz in DURAN® glass, the flask is offered as one piece and weighs 0,325 kg. Three-necked round-bottom flasks with this joint layout serve organic and inorganic laboratories, process development and teaching settings where robust multi-port access is required. Defined centre and side-neck sizes ensure compatibility with matching adapters, stoppers and ancillary glassware. Explicit joint dimensions simplify apparatus planning for multi-component setups. The pack size of 1 pc makes the vessel practical for equipping a workstation or replacing glassware in established closed-system assemblies used for controlled laboratory 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®, 1000 ml, side necks 29/32, centre 45/40
What is this article?
Three-necked round-bottom flask, DURAN®, 1000 ml, side necks 29/32, centre 45/40 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.
