Description
Three-necked round-bottom flask, 2000 ml is a multi-neck laboratory vessel intended for reaction, distillation and synthesis work requiring several ports at once. The flask combines a centre neck with ground joint 29/32 and two side necks with ground joint 14/23, enabling simultaneous connection of condensers, dropping funnels, thermometers or related accessories. Side necks are angled, which helps keep apparatus separated and improves handling on the laboratory bench. Made from DURAN® glass by manufacturer Lenz, it forms part of the established family of round flasks with ground glass joints used across chemical laboratories. With a 2000 ml nominal capacity, the vessel supports medium-volume preparations, and the round-bottom shape assists uniform heating and mixing with standard mantles or baths. Supplied as 1 pc(s), the unit weighs 0,528 kg. Common NS joint sizes allow straightforward mating with existing glassware trains for multi-step reactions, reflux setups and preparative procedures in research, development and teaching laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Three-necked round-bottom flask, 2000 ml, Centre neck 29/32, side neck 14/23
What is this article?
Three-necked round-bottom flask, 2000 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.
