Description
Long ground joint socket NS 19/38 is a laboratory glassware fitting designed for standard taper joint connections. It features an outer diameter of 22 mm, a length of 125 mm and a wall thickness of 1,8 mm, forming a long female ground-joint socket (Langschliffhülse) for NS 19/38 apparatus. Offered as a single piece with a net weight of 0,03 kg, the component is part of the Normschliff (standard ground joint) range widely employed in chemical laboratories. The elongated socket profile supplies extended contact length when paired with corresponding NS 19/38 cones, condensers or reaction vessels. Clear dimensional definition—outer diameter 22 mm, length 125 mm, wall thickness 1,8 mm—ensures compatibility with existing glassware of the same nominal size. Manufactured by Witeg and originating from Germany, the socket supports modular assembly of distillation, reflux and multi-piece laboratory systems. Its single-unit pack size simplifies inventory management for teaching, research and routine analytical workstations that rely on interchangeable NS 19/38 ground-glass connections. The part is ready for direct integration into standard laboratory glass apparatus.

Questions about Socket ST 19/38, full length, A-Ø 22 mm,
What is this article?
Socket ST 19/38, full length, A-Ø 22 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.
