Description
DURAN® Spherical Joint Socket, imperial size S 51/30, is a precision borosilicate glass 3.3 component for flexible laboratory glass connections. Spherical joints manufactured to DIN 12244 and DIN 12264 permit angular movement of up to 15° depending on joint size; tightness may decrease at angles greater than 5°. The nominal size is defined by the nominal diameter of the spherical joint and, where applicable, the clear width of the tube. Joint grease or PTFE sleeves should be used to ensure proper sealing, and spherical joint clamps with locking screws are recommended to secure the connection. This non-self-supporting glass article from manufacturer Duran/DWK Life Sciences is supplied for further processing and installation in glass apparatus. Greater joint flexibility improves releasability relative to rigid ground joints. The socket is suitable for vacuum applications and for building custom glass devices. Delivered as a single piece with a net weight of 0,093 kg, it enables reliable, adjustable couplings in laboratory setups requiring limited angular freedom.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

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.
