Beschrijving
Long ground joint socket NS 5/20 is a precision laboratory glassware component for apparatus that relies on standardised conical ground-joint connections. The socket features an outer diameter of 8 mm, an overall length of 120 mm and a wall thickness of 0,8 mm, giving an extended engagement length for secure mating with matching NS 5/20 cones. This slender long-socket design suits compact and micro-scale assemblies where a reliable, interchangeable joint is required. In distillation, reaction and transfer setups the NS 5/20 format supports modular glass trains without permanent seals. Produced by manufacturer Witeg, the piece integrates into systems built around the NS joint standard and helps maintain alignment in vertical or angled configurations. Supplied as a single piece, it is intended for laboratory glassware constructions that need a long ground joint rather than a short socket. Controlled dimensions and wall thickness balance mechanical stability with ease of incorporation into custom apparatus. The long ground joint socket NS 5/20 is a practical building block for leak-resistant, interchangeable connections in everyday laboratory glasswork.

Questions about Socket ST 5/20, full length, A-Ø 8 mm,
What is this article?
Socket ST 5/20, full length, A-Ø 8 mm, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Destillatiekoppen, adapters & kolommen, inside Destillatie- & extractieglaswerk, in Labmateriaal.
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.
