Description
Tubes with standard ground joint featuring a spherical connection S 51 are laboratory glassware components made from DURAN®. They form part of the glass tubes and capillaries range used to build and extend distillation, extraction and other modular laboratory glass assemblies. The spherical S 51 connection offers a defined coupling interface for matching spherical joint counterparts, enabling structured multi-piece apparatus layouts. Supplied as 1 pc(s) with a weight of 0,120 kg, the tube is convenient to keep on hand for apparatus construction or replacement work. These tubes from manufacturer Lenz suit laboratories that standardise on ground-joint geometry with spherical S 51 connections for flexible glass line design. Typical applications include joining sections of distillation trains, extraction setups and related transfer or process glassware that depend on interchangeable spherical joints. DURAN® denotes the glass quality specified for this component. Clear sizing to spherical connection S 51 supports consistent joint selection when technicians assemble, modify or service glass apparatus in research, analytical and teaching laboratories.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint, connection (spherical) S 51, DURAN®, 1 unit(s)
What is this article?
Tubes with standard ground joint, connection (spherical) S 51, DURAN®, 1 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.
