Description
SVS Screw Connection NS 14/23 is a precision laboratory glassware adapter that links a standard ground joint to a screw-thread interface. It combines a cone joint NS 14/23 with a GL 25 thread as an SVS thread transition piece, supplied as glass parts only and manufactured in accordance with DIN 12257. The single-piece unit has a net weight of 0,023 kg and is intended for modular assembly of reaction vessels, condensers, distillation trains and transfer lines where a secure screw coupling is preferred over a plain ground joint. In everyday laboratory practice the NS 14/23 cone mates directly with matching sockets, while the GL 25 thread accepts compatible screw caps and connectors, supporting leak-tight connections under typical atmospheric or mild vacuum conditions. This adapter from manufacturer Witeg is suited to organic and inorganic synthesis, analytical sample preparation and teaching laboratories that rely on interchangeable glass components. Its compact geometry simplifies storage on crowded benches and integration into existing glassware sets without additional reduction pieces.

Questions about Screw-thread, with cone ST 14/23
What is this article?
Screw-thread, with 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.
