Description
SVS Screw Connection NS 34/35 is a laboratory glass adapter featuring a standard ground joint core NS 34/35 and GL 25 thread. Designed as glass parts only according to DIN 12257, this SVS threaded screw connection enables reliable transitions between Normschliff ground-joint systems and screw fittings. The single-piece unit weighs 0,03 kg net and is intended for use as a transition piece or screw coupling in chemical, analytical and preparative glassware assemblies. With the NS 34/35 core it mates directly to matching ground joints while the GL 25 thread allows attachment of tubing, caps or accessories. Manufactured by Witeg, the connector supports distillation, reaction and vacuum apparatus where interchangeable ground joints and screw couplings are required. The glass-only construction without additional components keeps the fitting simple and dimensionally consistent with DIN 12257. Suitable for research and industrial laboratories that rely on standardised laboratory glassware, it provides a straightforward link between larger NS joints and GL-threaded connections in everyday experimental setups.

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