Description
4-Neck flask 2000 ml with centre neck NS 29/32 and three side necks NS 29/32 angled is a multi-neck laboratory vessel intended for large-volume distillation, synthesis and multi-port reaction setups. Fabricated from borosilicate glass 3.3, it delivers strong chemical resistance together with the thermal stability required for routine laboratory heating and cooling. The centre neck features a standard ground joint NS 29/32, while the three side necks of identical NS 29/32 size are angled at 7° to permit easy connection of condensers, dropping funnels, thermometers or gas inlets without crowding. Nominal volume is 2000 ml (2 l) and net weight is 0,600 kg, making the flask suitable for scale-up preparative work. This four-neck configuration from manufacturer Rettberg allows simultaneous reagent addition, temperature control and vapour management in a single vessel. It is commonly employed as a round-bottom distillation flask or receiving flask within standard ground-joint assemblies in 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, 2000 ml, mn size 29/32, 3x sn size 29/32 (7°)
What is this article?
4-neck flask, 2000 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.
