Description
SVS screw connection with cone NS 14/23 is a glass laboratory fitting that combines a standard ground joint cone NS 14/23 with a screw-thread connection. Manufactured to DIN 12257 with GL 14/6 thread and a 12 × 6 seal, the component has an overall length of 55 mm and is supplied as the glass part only. This transition piece enables secure, leak-resistant coupling between ground-joint glassware and screw-thread accessories in chemical and analytical setups. The compact design and precise NS 14/23 cone ensure compatibility with common laboratory apparatus while the GL 14/6 thread accepts matching screw caps or connectors. Offered as a single piece from manufacturer Witeg, the fitting is intended for modular glass assemblies where a reliable screw-to-cone interface is required. Net weight is 0,007 kg, making the part light and easy to integrate into existing apparatus. Ideal for distillation, reaction or transfer lines that need both ground-joint and screw-thread connectivity without additional adapters.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Screw-thread, with cone ST 14/23
What is this article?
Screw-thread, with cone ST 14/23 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.
