Description
SVS screw connection NS 24/29 is a glass laboratory adapter that joins a standard ground cone joint to a screw-thread interface. Equipped with a cone NS 24/29 and a GL 14/6 thread, it enables secure attachment of tubing, caps or accessories to apparatus built around the NS 24/29 joint size. The seal measures 12 × 6 mm and the overall length is 65 mm; the item is supplied as the glass part only. This transition piece from manufacturer Witeg is intended for modular glass systems used in synthesis, distillation and analytical work where a reliable changeover from conical ground joints to screw couplings is required. The defined geometry supports reproducible assembly of vacuum lines, condensers or transfer paths while maintaining compatibility with common laboratory glassware. Net weight is 0,016 kg. By combining the widely used NS 24/29 cone with a GL 14 thread, the SVS screw connection offers a practical interface for laboratories that need flexible, standardised connections without redesigning existing set-ups.

Questions about Screw-thread, with cone, cone ST 24/29
What is this article?
Screw-thread, with cone, cone ST 24/29 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.
