Description
Spherical joint socket KS 29/15 is a precision laboratory glassware component for flexible ball-and-socket connections. Made from DURAN tubing, it carries the KS 29/15 joint designation and measures 19 × 120 × 1,8 mm. The socket forms the female half of a spherical ground-joint pair, allowing limited angular movement in vacuum lines, distillation trains and multi-joint assemblies where rigid alignment is impractical. Offered as a single piece with a net weight of 0,029 kg, this part from manufacturer Witeg suits chemical, analytical and teaching laboratories that rely on modular glass apparatus. DURAN tubing provides the thermal and chemical resistance expected for routine laboratory glassware. When mated with a matching spherical joint ball and appropriately greased, the KS 29/15 geometry supports a reliable, adjustable seal. The component integrates readily into existing spherical-joint systems used across research and industrial lab environments that require interchangeable, movement-tolerant glass connections without compromising joint integrity.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

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.
