Description
SVS Screw Connection NS 34/35 is a laboratory glass adapter that links standard ground-joint apparatus to screw-thread systems. It combines an NS 34/35 core with a GL 14 thread as an SVS thread transition piece, allowing secure, leak-resistant coupling in distillation, reaction and transfer setups. The component is supplied as a single piece with a net weight of 0,028 kg and is intended for modular glassware assemblies where standardised NS joints must interface with GL-threaded fittings. Produced by Witeg, this screw connection supports chemical and analytical workflows that demand dimensional accuracy and chemical resistance typical of laboratory borosilicate glassware. Categories of use include transition pieces, ground-joint reducers and screw couplings. The design simplifies apparatus reconfiguration without additional adapters, helping maintain joint integrity across multi-component lines. Suitable for research, quality-control and teaching laboratories, the SVS Screw Connection NS 34/35 provides a compact, reliable interface between cone joints and screw connections in everyday glass apparatus.

Questions about Screw-thread, with cone, cone ST 34/35
What is this article?
Screw-thread, with cone, cone ST 34/35 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.
