Description
Tubes with standard ground joint and spherical connection S 13/2 are laboratory glass components for building modular apparatus in distillation, extraction and related workflows. Produced in DURAN® borosilicate glass, they combine a standard ground joint interface with a spherical S 13/2 connection for flexible coupling within glass trains. These tubes support transfer, linking and intermediate sections where spherical joints improve alignment tolerance compared with rigid conical-only setups. Packaged as 10 pc(s) with a total weight of 0,148 kg, they suit stock replenishment for teaching laboratories, research groups and preparative facilities. The tubes from manufacturer Lenz fall within glass components used for distillation and extraction assemblies. DURAN® glass offers the thermal and chemical durability expected in routine laboratory glassware service. Consistent S 13/2 spherical geometry across the pack helps standardize connections and simplifies replacement of individual sections without redesigning the full apparatus layout.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint, connection (spherical) S 13/2, DURAN®
What is this article?
Tubes with standard ground joint, connection (spherical) S 13/2, 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?
