Description
Tubes with standard ground joint and spherical connection S 19 in DURAN® glass are laboratory glass components intended for modular apparatus work. They provide a defined spherical S 19 interface together with a standard ground joint, supporting secure coupling in glass assemblies used for distillation, extraction and related laboratory setups. The pack contains 10 pc(s) and has a weight of 0,240 kg, which is practical for stocking a frequently used joint size. These tubes sit in the laboratory glassware range for vessels, consumables and glass components, and are suitable wherever interchangeable spherical ground-joint connections are required. Manufactured by Lenz, they fit routine research, teaching and quality-control environments that rely on standardised glass joints. DURAN® identifies the glass type specified for the product. Clear joint designation and multi-piece packaging help laboratories maintain consistent inventory for apparatus construction, maintenance and replacement. Select these spherical S 19 tubes when assembling or servicing glass systems that call for this connection size in distillation and extraction configurations.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint, connection (spherical) S 19, DURAN®
What is this article?
Tubes with standard ground joint, connection (spherical) S 19, DURAN® is the article on this page. Luminix Health distributes Lenz 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.
