Description
SVS Screw Connection NS 29/32 is a laboratory glass transition piece that joins a standard ground joint to a screw-thread interface. Equipped with a core NS 29/32 and a GL 18/8 thread, it enables reliable coupling between conical-joint glassware and GL-compatible closures. The seal measures 16 × 8 mm and the overall length is 75 mm; only the glass part is supplied. Conforming to DIN 12257 and weighing 0,023 kg net, the adapter is suited to distillation, reflux and general synthesis assemblies where dimensional accuracy and chemical resistance are essential. From manufacturer Witeg, this SVS screw connection serves as a practical reducer and screw coupling within modular laboratory glass systems. It supports clean, leak-resistant transitions without introducing extraneous materials into the process stream. Typical applications include organic synthesis lines, sample preparation manifolds and apparatus that must interchange between NS joints and threaded fittings while preserving a compact footprint and straightforward assembly.

Questions about Screw-thread, with cone, cone ST 29/32
What is this article?
Screw-thread, with cone, cone ST 29/32 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.
