Description
DURAN® spherical ground joints according to DIN 12244 and 12264 are used to produce flexible connections of up to 15° - depending on the size of the ground joint. From an angle > 5°, a reduction in tightness must be expected. The nominal size is composed of the nominal diameter of the spherical ground joint and, if applicable, the clear width of the pipe diameter. Ground joints with ground grease or PTFE sleeves should always be used. Ball joint clamps with locking screw are the perfect addition to secure the ball joint.
Features and Benefits:
- According to DIN 12244 and 12264
- Flexible connections of up to 15° can be realised depending on the size of the cut (angle ? tightness reduced)
- Better detachability due to greater flexibility of the ground joint
- The nominal size describes the nominal diameter of the spherical ground joint.
- Not self-supporting
- Glass articles for further processing
Application: Suitable for vacuum applications, Installation in glass apparatus and devices

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 Matériel de laboratoire.
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.
