Description
Two-neck adapter with cone NS 29/32 and two sockets NS 29/32 is a distillation glassware component featuring parallel necks. Made from borosilicate glass 3.3, the adapter supplies two upper ground-joint ports while the lower cone mates with standard NS 29/32 apparatus. The parallel-neck arrangement permits concurrent connection of additional items such as dropping funnels, condensers or sensors without spatial conflict. Delivered as a single piece with a net weight of 0,142 kg, it is designed for laboratory distillation and multi-neck reaction assemblies. This two-neck adapter originates from manufacturer Rettberg and bears the Rettberg ® trademark. Classified among distillation adapters, it guarantees compatibility with widely used European ground-joint systems. Borosilicate glass 3.3 confers the chemical resistance and thermal durability required for organic synthesis, fractional distillation and preparative chemistry. Laboratories can incorporate the adapter into existing glassware setups that need dual upper connections on an NS 29/32 base joint.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 2-neck adapter, cone size 29/32, 2x socket size 29/32,
What is this article?
2-neck adapter, cone size 29/32, 2x socket size 29/32, 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.
