Description
Spherical joint socket KS13/5 is a laboratory glassware fitting intended for precise spherical joint connections in chemical apparatus. Produced from DURAN tubing to the KS 13/5 specification, it measures 8 × 100 × 1,5 mm and delivers a consistent fit together with the chemical durability expected of borosilicate laboratory glass. The single-piece unit has a net weight of 0,009 kg and is well suited to modular glass setups that rely on spherical joints for flexible angular positioning. DURAN construction offers good thermal stability and inertness, making the socket appropriate for vacuum lines, distillation apparatus, and reaction assemblies. This spherical joint socket from manufacturer Witeg mates with corresponding spherical joint balls to enable rapid, reproducible assembly and disassembly. Its standardised KS geometry supports leak-resistant connections in organic synthesis, analytical sample work, and process-development laboratories where reliable joint performance is required.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Spherical joints socket member S 13/5
What is this article?
Spherical joints socket member S 13/5 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labware.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
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.
