Description
Long ground joint socket NS 12/32 is a laboratory glassware fitting designed for standardised conical ground-joint assemblies. It offers an outer diameter of 15 mm, a length of 120 mm and a wall thickness of 1,8 mm, providing a robust long socket for secure engagement with corresponding NS 12/32 cones. The extended ground section improves alignment and sealing performance in distillation, reaction and transfer apparatus built on interchangeable NS joints. This size is well suited to medium-scale laboratory setups that need a durable, modular connection. From manufacturer Witeg, the socket supports construction of custom glass trains where leak-resistant joints without permanent fixation are preferred. Supplied as one piece, it fits into systems that follow the NS joint standard and benefits from the longer engagement length compared with short sockets. The defined outer diameter and wall thickness give mechanical stability while remaining practical for routine glassblowing and apparatus assembly. Long ground joint socket NS 12/32 is a reliable component for laboratories assembling or maintaining modular glassware with NS 12/32 connections.

Questions about Socket ST 12/32, full length, A-Ø 15 mm,
What is this article?
Socket ST 12/32, full length, A-Ø 15 mm, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Têtes de distillation, adaptateurs & colonnes, inside Verrerie de distillation & d'extraction, in Matériel de laboratoire.
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.
