Description
SVS Screw Connection NS 34/35 is a glass thread-transition adapter designed for laboratory apparatus that must bridge a standard ground joint and a GL screw interface. It features a core joint NS 34/35 together with a GL 18 thread, forming an SVS screw-connection piece supplied as the glass part only. Manufactured in accordance with DIN 12257 and weighing 0,028 kg net, the component provides a compact, chemically resistant link for distillation, synthesis and general glassware assemblies. From manufacturer Witeg, the adapter belongs to the category of transition pieces, standard-ground reducers and screw couplings used throughout chemical and analytical laboratories. Its SVS configuration allows clean interchange between conical NS joints and threaded closures while keeping the wetted path free of additional metal or polymer inserts. The piece is well suited to modular setups that require reliable, leak-resistant connections, straightforward assembly and dimensional consistency across larger joint sizes in routine laboratory workflows.

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.
