Beschreibung
Spherical joint socket KS 29/15 is a grease-free, flexible laboratory glass joint component for secure spherical ground-joint assemblies. Made from borosilicate glass 3.3, this Rotulex-system socket delivers a reliable KS 29/15 connection without grease, reducing contamination risk and simplifying cleaning between runs. The spherical geometry allows limited angular movement while maintaining a tight seal, which is useful in vacuum lines, distillation setups and multi-neck reaction apparatus. Supplied as one piece with a net weight of 0,037 kg, the socket belongs to the Rotulex range from manufacturer Rettberg and is intended for pairing with the matching ball joint. Borosilicate glass 3.3 provides high thermal-shock resistance and broad chemical compatibility, supporting everyday organic synthesis, preparative work and general laboratory glassware systems. The grease-free design is especially practical where residue-free joints or frequent reconfiguration are required. This KS 29/15 socket offers a durable, chemically robust interface for research and industrial laboratory environments that rely on flexible spherical joint connections.

Questions about Spherical joint cup size 29/15, for grease-free, flexible connection,
What is this article?
Spherical joint cup size 29/15, for grease-free, flexible connection, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Laborbedarf.
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.
