Description
Two-neck adapters NS 24/29 are laboratory distillation fittings featuring parallel necks, a ground joint cone NS 24/29 and sockets NS 19/26. These adapters allow simultaneous connection of additional apparatus such as condensers, dropping funnels or thermometers to a reaction flask while preserving a compact layout. The parallel neck geometry supports multi-port configurations commonly required in organic synthesis, fractional distillation and reflux procedures. Supplied as a single piece with a net weight of 0,063 kg, the unit integrates readily into standard European NS joint glassware systems. Produced by manufacturer Witeg, the adapters are intended for preparative chemistry, solvent recovery and teaching laboratories that rely on reliable taper-joint seals under atmospheric or mild vacuum conditions. Precise NS dimensions ensure mechanical compatibility with matching flasks and accessories, facilitating stable assemblies for separation techniques and multi-step reactions. The design provides convenient side access without obstructing the main vapour path, making the adapters a practical choice for routine laboratory distillation setups.

Questions about Multiple adapters, with two parallel nec
What is this article?
Multiple adapters, with two parallel nec is the article on this page. Luminix Health distributes Witeg 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.
