Description
Tubes with standard ground joint 14/23 are laboratory glass tubes finished with a precision socket for compact, interchangeable connections in small-scale glass apparatus. Each tube is 130 mm in length and made of DURAN® glass, supporting everyday chemical work where dimensional consistency and resistance to common laboratory reagents are important. The 14/23 standard ground joint socket accepts matching cones, stoppers, adapters, and other NS 14/23 components used in micro-distillation, extraction, drying trains, and teaching setups. Supplied as 10 pieces per pack from manufacturer Lenz, these sockets help laboratories keep a ready inventory of frequently used joint sizes for rapid apparatus changes. Socket geometry provides a stable female interface that seats cleanly when joints are properly prepared, reducing the need for improvised seals during routine assembly. Pack weight is 0,250 kg, convenient for shelf storage and kit preparation. Application areas include laboratory glassware and vessels, glass components for distillation and extraction, and tubes or capillaries where a defined 14/23 socket is specified. The format suits research groups, analytical labs, and educational benches that rely on standardized ground-glass connections for reproducible, modular builds.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint Sockets with ground glass joint, 14/23, 130 mm
What is this article?
Tubes with standard ground joint Sockets with ground glass joint, 14/23, 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 Matériel de laboratoire.
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.
