Description
Four-necked round bottom flask, 1000 ml is a DURAN® laboratory flask with a centre neck NS 29/32 and side neck NS 29/32 arranged as parallel side necks for multi-port reaction and process set-ups. The one-litre round-bottom body promotes even heat distribution and thorough mixing when used with heating mantles, oil baths or other standard laboratory heaters. Parallel side necks ease mounting of condensers, addition funnels, temperature probes and stirrers while keeping joints aligned for stable apparatus assembly. Supplied as a single piece weighing 0,430 kg, the flask from manufacturer Lenz integrates with NS 29/32 ground-glass accessories common in synthesis laboratories. It is intended for organic reactions, reflux work, controlled reagent addition and multi-inlet distillations where four access points reduce reliance on adapters. DURAN® glass construction supports everyday laboratory handling in research, development and teaching environments that depend on interchangeable jointed glassware for flexible, closed-system experiments.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Four-necked round bottom flask, 1000 ml, centre neck NS 29/32
What is this article?
Four-necked round bottom flask, 1000 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.
