Description
Three-necked round-bottom flask, 6000 ml is a large-capacity multi-neck laboratory vessel for preparative reactions, distillations and scale-up work. It is made from DURAN® glass and combines a centre neck with ground joint NS 29/32 and two angled side necks with ground joints NS 14/23, allowing simultaneous connection of condensers, dropping funnels, thermometers, stirrer guides or gas inlets without crowding the working space. The round-bottom profile promotes uniform heat transfer when the flask is used with heating mantles or oil baths and supports efficient mixing of larger reaction volumes. Angled side necks improve apparatus layout and reduce interference between attached glassware. Supplied as a single piece from manufacturer Lenz, the flask weighs 1,386 kg and suits organic synthesis, process development and teaching laboratories that require robust multi-port flasks compatible with standard ground-joint systems. The 6000 ml working volume supports batch chemistry and pilot-scale experiments where reliable joint geometry and thermal stability are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 6000 ml, Centre neck 29/32, side neck 14/23
What is this article?
Three-necked round-bottom flask, 6000 ml, Centre neck 29/32, side neck 14/23 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.
