Description
4-Neck flask 1000 ml with centre neck NS 29/32 and three side necks NS 29/32 angled is a multi-neck laboratory vessel designed for larger-scale distillation, synthesis and multi-port reaction work. Constructed from borosilicate glass 3.3, the flask offers reliable chemical resistance and thermal performance under typical laboratory conditions. The central neck is fitted with a standard ground joint NS 29/32; the three side necks share the same NS 29/32 joint size and are angled at 7° for unobstructed attachment of condensers, addition funnels, probes or inert-gas lines. Nominal volume is 1000 ml (1 l) and net weight is 0,368 kg, providing ample capacity for preparative procedures. This four-neck design from manufacturer Rettberg enables concurrent reagent dosing, temperature monitoring and vapour handling within one vessel. It functions effectively as a round-bottom distillation flask or receiving flask in ground-joint apparatus used throughout organic and preparative chemistry laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 4-neck flask, 1000 ml, mn size 29/32, 3x sn size 29/32 (7°)
What is this article?
4-neck flask, 1000 ml, mn size 29/32, 3x sn size 29/32 (7°) is the article on this page. Luminix Health distributes Rettberg 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.
