Description
Tubes with standard ground joint, ball (spherical) S 19, DURAN® are precision laboratory glass parts for building distillation and extraction apparatus. The pack comprises 10 pc(s) of tubes equipped with a spherical ball joint size S 19, designed for standardised coupling to compatible ground-joint sockets in modular glass systems. These DURAN® tubes belong to laboratory glass, vessels and consumables and are grouped with glass components, tubes and capillaries used in scientific workflows. From manufacturer Lenz, they offer a practical unit quantity for laboratories maintaining stocks of jointed glassware. Pack weight is 0,155 kg, supporting straightforward handling and storage on the bench or in glassware cabinets. The spherical ball S 19 geometry identifies the joint clearly for matching within multi-piece assemblies where consistent standard ground joints are required. Suitable for research, teaching and process laboratories that rely on DURAN® components for distillation trains, extraction setups and related vessel connections. Selecting the S 19 size helps keep apparatus configurations interchangeable across the same joint family while remaining within established laboratory glassware practice.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint, ball (spherical) S 19, DURAN®, 10 unit(s)
What is this article?
Tubes with standard ground joint, ball (spherical) S 19, DURAN®, 10 unit(s) 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.
