Description
SVS Screw Connection NS 14/23 is a compact laboratory glass adapter that joins standard ground-joint glassware to screw-thread components. It features a GL 18 thread and an NS 14/23 core, with an overall length of 60 mm, and is supplied as the glass part only. This configuration enables secure coupling in small-scale distillation, reaction and sample-transfer lines where space and joint compatibility matter. The single-piece unit has a net weight of 0,012 kg and fits modular assemblies that combine NS cones with GL-threaded fittings. From manufacturer Witeg, the connector is suited to chemical and analytical work requiring reliable glass interfaces and dimensional consistency. Typical applications include transition pieces, ground-joint reducers and screw couplings in research and quality-control laboratories. By providing a direct SVS screw connection with an NS 14/23 core, the adapter reduces the need for extra intermediate pieces and supports stable apparatus layouts. Ideal for routine laboratory glass systems that must bridge cone joints and screw connections cleanly and repeatably.

Questions about Screw-thread, with cone, cone ST 14/23
What is this article?
Screw-thread, with cone, cone ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
