Description
Spherical joint securing system KS 19/9 made of POM is a laboratory clamp accessory for holding spherical ground-glass joints securely together. Sized for the KS 19/9 spherical joint standard, the clip is manufactured from polyoxymethylene (POM) and provides a simple mechanical lock that keeps ball-and-socket joints engaged during assembly, vacuum work or solvent handling. Supplied as a single piece with a net weight of 0,053 kg, it belongs to the ground-joint connection product group and is intended for routine glassware set-ups that use spherical joints. This securing system from manufacturer Rettberg offers a lightweight, chemically resistant alternative to metal clips for KS 19/9 connections. Typical applications include distillation, reaction and vacuum apparatus where reliable retention of spherical joints is required without tools. The POM construction combines dimensional stability with good resistance to many laboratory chemicals, supporting repeated use on standard KS 19/9 glassware. Product type is ground-joint connections; the design matches common laboratory spherical joint sizes used in research and teaching laboratories.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Spherical joint safety system KS 19/9, made of POM
What is this article?
Spherical joint safety system KS 19/9, made of POM 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 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.
Which category should I open next?
