Description
Joint clips for spherical joint KS 35, light orange, are specialised laboratory clamps made from polyacetal (POM), known under the Delrin® trademark. Designed for KS 35 spherical ground joints, they offer a melting point of 175 °C, heat resistance up to approximately 150 °C and very good chemical resistance. The clips are light, secure and quick to fit and remove, allowing efficient handling of glass apparatus without damaging the glass surface. Their construction resists bending so the form stays constant over repeated use, and the polyoxymethylene material shows no corrosion under typical laboratory conditions. Colour coding by size—here light orange for the KS 35 format—enables rapid visual distinction between different joint sizes on the bench or in storage. These joint clips from manufacturer IDL GmbH are supplied as a single piece and support reliable assembly of spherical-joint glassware in chemical synthesis, distillation and analytical laboratories where secure, non-marring fixation of ground joints is required.

Questions about Ground glass joint clamp for spherical glass joint, KS 35, light orange
What is this article?
Ground glass joint clamp for spherical glass joint, KS 35, light orange is the article on this page. Luminix Health distributes IDL GmbH for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
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.
