Description
SVS Screw Connection NS 29/32 is a laboratory glass adapter with a standard ground joint core NS 29/32 and GL 25/10 thread. Supplied as the glass component only and without seal, it follows DIN 12257 and measures 75 mm in length. This SVS screw connection serves as a transition piece between Normschliff ground-joint systems and threaded GL fittings, supporting secure couplings in distillation, reaction and vacuum glassware assemblies. The single-piece unit has a net weight of 0,025 kg and is intended for use where screw couplings and ground-joint reductions are required in chemical and analytical laboratories. Produced by Witeg, the connector integrates the NS 29/32 core with the GL 25/10 thread so that tubing, caps or accessories can be attached while maintaining compatibility with standard laboratory glassware. Suitable for research and industrial setups that rely on interchangeable ground joints and screw fittings, it provides a straightforward glass-only link without additional sealing elements. The design focuses on dimensional conformity to DIN 12257 for reliable interchangeability across common laboratory apparatus.

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