Description
Tubes with standard ground joint 19/26 are laboratory glass tubes fitted with a precision socket joint for versatile assembly of distillation, extraction, and general preparative glassware. Measuring 130 mm in length and manufactured from DURAN® glass, they provide a durable female interface for matching cones, stoppers, adapters, and related NS 19/26 components. The 19/26 standard ground joint is a common intermediate size in European laboratory practice, bridging smaller micro-scale joints and larger process connections while remaining easy to handle on the open bench or in a fume hood. Available in packs of 10 pieces from manufacturer Lenz, the tubes support stockrooms and teaching collections that standardize on interchangeable ground-glass parts. Socket geometry allows secure seating and straightforward separation when joints are clean and correctly prepared, supporting flexible apparatus layouts without permanent glassblowing for every configuration change. The pack weight is 0,300 kg, practical for inventory and kit assembly. These items belong with laboratory glass vessels and consumables, glass components for distillation and extraction, and tubes or capillaries specified with a 19/26 socket for reliable, modular coupling in research, quality control, and instructional laboratories.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint Sockets with ground glass joint, 19/26, 130 mm
What is this article?
Tubes with standard ground joint Sockets with ground glass joint, 19/26, 130 mm 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.
