Description
SVS screw connection with cone NS 19/26 is a laboratory glassware transition piece that links standard ground-joint apparatus to screw-thread fittings. It combines a precision cone joint NS 19/26 with a GL 14/6 thread manufactured to DIN 12257, allowing secure coupling of glassware to tubing, caps or accessories in distillation, reaction and analytical set-ups. The component incorporates a seal of 12 × 6 mm and has an overall length of 60 mm; only the glass part is supplied, ready for use with matching screw fittings. This adapter from manufacturer Witeg belongs to the family of ground-joint reducers and screw couplings used to build modular laboratory systems. Its compact form and defined joint geometry support reproducible assembly of vacuum lines, condensers or sample-transfer paths where an NS 19/26 cone must interface with a GL thread. Net weight is 0,011 kg, making the piece easy to handle and store. The SVS design provides a practical, standardised solution for laboratories that require reliable transitions between conical ground joints and screw connections without altering existing glassware inventories.

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