Description
DURAN® spherical joint ball, imperial size S 64/40 is a precision borosilicate glass 3.3 component for creating flexible laboratory connections. Conforming to DIN 12244 and DIN 12264, these spherical joints allow bendable, flexible joints of up to 15° depending on joint size; angles above 5° may reduce tightness. The nominal size combines the nominal diameter of the spherical joint with the clear tube diameter where applicable. Joint grease or PTFE sleeves should be used with the ground surfaces, while spherical joint clamps with locking screws securely hold the assembly. Better releasability results from the inherent flexibility of the connection. This glass article from manufacturer Duran/DWK Life Sciences is supplied for further processing, is not self-supporting, and is suitable for vacuum applications as well as incorporation into glass apparatus and instruments. Supplied as a single piece with a net weight of 0,205 kg, it supports reliable, adjustable linkages in laboratory glassware systems requiring limited angular movement.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about DURAN® Spherical Joint, ball inches size
What is this article?
DURAN® Spherical Joint, ball 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?
