Description
Tubes with standard ground joint and spherical connection S 13/5 are glass laboratory tubes for assembling modular systems used in distillation, extraction and general glassware trains. Made from DURAN® borosilicate glass, each tube pairs a standard ground joint with a spherical S 13/5 connection to support flexible, well-aligned couplings between apparatus sections. They are suited to transfer lines, intermediate links and custom setups where spherical joints accommodate slight angular variation better than fixed conical joints alone. The pack contains 10 pc(s) and weighs 0,120 kg in total, which is practical for laboratory inventory and shared glassware stores. These tubes from manufacturer Lenz are part of the glass components range for distillation and extraction work. DURAN® construction provides the chemical and thermal performance required for everyday laboratory service. Uniform S 13/5 spherical connections across the set help maintain interchangeable sections and streamline replacement within established glassware configurations.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint, connection (spherical) S 13/5, DURAN®
What is this article?
Tubes with standard ground joint, connection (spherical) S 13/5, 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.
Which category should I open next?
