Description
Spherical joint socket KS 35/20 is a precision laboratory glassware component for reliable spherical ground-joint connections in chemical and analytical setups. Designed as the socket (Schale) half of a ball-and-socket joint pair, it follows the dimensional and interchangeability requirements of DIN 12244 and DIN 12266, supporting consistent alignment and sealing when mated with the matching ball joint. The KS 35/20 size designation identifies the nominal joint geometry used across standard lab assemblies for apparatus that must be connected, disconnected, or adjusted without rigid alignment constraints. Supplied as a single piece, this socket is suited to vacuum lines, reaction trains, distillation and filtration glassware, and modular apparatus where spherical joints reduce stress compared with conical ground joints. Manufactured by Schlee, the component integrates into existing DIN-compatible spherical-joint inventories and is intended for routine laboratory material use. Clear size marking (KS 35/20) aids quick selection and replacement during apparatus build-up or maintenance. Ideal for research, teaching, and quality-control laboratories that rely on standardised spherical joints for flexible, leak-conscious connections.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Spherical joints according DIN 12244/12266, cup KS 35/20
What is this article?
Spherical joints according DIN 12244/12266, cup KS 35/20 is the article on this page. Luminix Health distributes Schlee 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.
