Description
DURAN® Spherical Joint Socket S 40/25 is a precision-engineered glass component fabricated from borosilicate glass 3.3 for establishing flexible spherical ground-joint connections in laboratory equipment. Compliant with DIN 12244 and DIN 12264, this imperial-size socket allows angular flexibility of up to 15° depending on the joint size, while angles exceeding 5° may reduce sealing integrity. The nominal size corresponds to the nominal diameter of the spherical joint. Supplied as a single unit with both net and gross weight of 0,049 kg, the item is intended for further processing into glass assemblies and is suitable for vacuum applications. Use of ground-joint grease or PTFE sleeves is advised for proper sealing; spherical joint clamps with locking screws provide secure fixation. The inherent flexibility of the spherical design enhances releasability. This non-self-supporting glassware component from manufacturer Duran/DWK Life Sciences is well suited for integration into custom glass apparatus requiring limited articulation and vacuum-compatible performance.

Questions about DURAN® Spherical Joint, cup inches size
What is this article?
DURAN® Spherical Joint, cup inches size is the article on this page. Luminix Health distributes DWK Life Sciences 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?
