Description
Four-necked round bottom flask, 4000 ml is a multi-neck laboratory vessel intended for reaction setups, distillations, and preparative procedures needing several simultaneous ground-joint connections. With a 4000 ml capacity, it accommodates substantial batch volumes in synthesis and scale-up work. The centre neck carries an NS 29/32 ground glass joint, and the side necks are likewise NS 29/32 joints set in a parallel arrangement, allowing condensers, dropping funnels, stirrers, and sensors to be fitted side by side. Produced from DURAN® glass by manufacturer Lenz, the flask is supplied as a single piece weighing 1,175 kg. Parallel side necks help keep connected glassware aligned on laboratory stands and heating mantles. Round-bottom construction supports even heat transfer and mixing during heating or reflux operations. This four-neck design suits organic chemistry laboratories, process development, and advanced practical courses that rely on standard NS taper joints. DURAN® material and matched joint sizes connect cleanly with common laboratory glassware systems used in routine experimental practice.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Four-necked round bottom flask, 4000 ml, centre neck NS 29/32
What is this article?
Four-necked round bottom flask, 4000 ml, centre neck NS 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 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.
