Description
SVS Screw Connection NS 19/26 is a laboratory glass adapter that connects standard ground-joint apparatus to screw-thread systems. It incorporates an NS 19/26 core with GL 18/8 threading, a seal dimension of 16 x 8 mm and a length of 60 mm, and is supplied as the glass part only without screw cap. Manufactured in accordance with DIN 12257, the piece supports secure, standardised coupling in distillation, reaction and transfer setups. The single unit weighs 0,012 kg net and is intended for modular glassware where NS cones must interface with GL-threaded fittings. Offered by Witeg, this SVS screw connection suits chemical and analytical laboratories that require dimensional accuracy and chemical resistance from glass transition components. It functions as a transition piece, ground-joint reducer or screw coupling, simplifying apparatus layout while preserving joint integrity. The defined seal size and DIN-compliant geometry help ensure reproducible assembly across multi-component lines. Suitable for research, quality-control and teaching environments needing a reliable NS 19/26 to GL screw interface.

Questions about Screw thread, with cone, ST 19/26, GL 1
What is this article?
Screw thread, with cone, ST 19/26, GL 1 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.
