Description
SVS Screw Connection NS 45/40 is a laboratory glass adapter with a standard ground joint core NS 45/40 and GL 25 thread. Measuring 100 mm in length and conforming to DIN 12257, this SVS screw connection serves as a transition piece between larger Normschliff ground-joint systems and threaded GL fittings. The single-piece unit has a net weight of 0,057 kg and is intended for screw couplings and ground-joint reductions in chemical and analytical glassware assemblies. The NS 45/40 core integrates with matching laboratory joints while the GL 25 thread permits secure attachment of tubing, caps or accessories. Produced by Witeg, the connector supports distillation, reaction and vacuum apparatus that require interchangeable ground joints and screw fittings. Its glass construction follows the dimensional requirements of DIN 12257 for reliable interchangeability across common laboratory setups. Suitable for research and industrial environments working with larger joint sizes, it provides a straightforward glass link between NS 45/40 systems and GL-threaded connections without unnecessary complexity.

Questions about Screw-thread, with cone ST 45/40
What is this article?
Screw-thread, with cone ST 45/40 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.
