Description
Spherical joint socket KS 29/15 Rotulex is a laboratory glassware socket for flexible spherical ground-joint connections. Produced from DURAN tubing in the Rotulex series, it is specified as KS 29/15 with dimensions 19 × 120 × 1,8 mm. The socket constitutes the female element of a ball-and-socket joint, enabling angular adjustment in vacuum apparatus, distillation setups and multi-joint glass systems where fixed alignment is unsuitable. Supplied as one piece with a net weight of 0,037 kg, the component from manufacturer Witeg is intended for chemical, analytical and teaching laboratories using modular glassware. DURAN tubing delivers the thermal and chemical durability required for everyday laboratory service. Paired with a corresponding spherical joint ball and suitable joint grease, the KS 29/15 Rotulex geometry provides a secure yet movable seal. It fits standard spherical-joint workflows in research and industrial environments that need interchangeable, movement-tolerant connections while maintaining joint integrity throughout the apparatus.

Questions about Spherical joints socket member S 29/15
What is this article?
Spherical joints socket member S 29/15 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.
