Description
Four-necked round bottom flask, 3000 ml is a multi-neck laboratory vessel for reaction, distillation, and preparative work that requires several ground-joint connections at once. The 3000 ml capacity supports larger working volumes in synthesis and process development. Its centre neck is finished with an NS 45/40 ground glass joint, while the side necks use NS 29/32 joints arranged in a parallel layout so condensers, dropping funnels, gas inlets, and temperature probes can be mounted together without crowding. Made from DURAN® glass and offered by manufacturer Lenz, the flask is supplied as one piece and weighs 0,980 kg. Parallel side-neck geometry keeps attached apparatus upright and accessible on stands and heating equipment. The round-bottom form aids uniform heating and effective mixing with magnetic or overhead stirrers. Organic chemistry laboratories, pilot-scale setups, and teaching environments that standardise on NS taper joints use this four-neck configuration for flexible multi-port assemblies. Defined joint sizes and DURAN® construction integrate readily with existing laboratory glassware systems for everyday experimental workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Four-necked round bottom flask, 3000 ml, centre neck NS 45/40
What is this article?
Four-necked round bottom flask, 3000 ml, centre neck NS 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 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.
