Description
Two-neck adapter with angled socket NS 19/26 is a glass laboratory fitting equipped with one angled socket, a cone joint NS 19/26 and sockets NS 14/23. This arrangement permits versatile multi-neck connections in distillation and reaction systems, enabling concurrent use of condensers, addition funnels or secondary vessels under closed conditions. The angled socket improves spatial access and reduces clutter on the laboratory bench during synthesis or fractionation procedures. Net and gross weight are each 0,052 kg, offering a balanced, manageable component for standard ground-joint assemblies. Manufactured by Witeg, the adapter ensures compatibility with common NS glassware trains employed in research and process laboratories. Reliable sealing at the specified joint sizes supports leak-free operation and efficient vapour or liquid transfer. Supplied as 1 pc, the two-neck design provides a practical solution for chemists requiring flexible, multi-port configurations in everyday laboratory workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Multiple adapters, two necks, cone ST
What is this article?
Multiple adapters, two necks, cone ST 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.
