Description
SVS screw connection NS 45/40 is a precision glassware adapter designed for secure threaded transitions in laboratory assemblies. It combines a ground cone joint NS 45/40 with a GL 32 thread, forming an SVS thread transition piece that enables reliable coupling between standard ground-joint apparatus and screw-thread components. Manufactured to DIN 12257 and supplied as glass parts only, the unit supports clean, chemically resistant connections in distillation, reaction and vacuum setups. This adapter from manufacturer Witeg is intended for routine laboratory use where a robust NS-to-GL interface is required. The single-piece glass construction ensures dimensional accuracy of the cone and thread, facilitating leak-minimised joints when used with appropriate seals and clamps. With a net weight of 0,052 kg, the component is compact yet sturdy enough for repeated assembly and disassembly. Ideal for organic synthesis benches, preparative work and general glassware systems that demand standardised NS 45/40 and GL 32 compatibility, it integrates smoothly into existing ground-joint lines without additional metal fittings.

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.
