Description
Tubes with standard ground joint 19/26 are laboratory glass tubes equipped with standard ground joint cones in size 19/26 and a length of 130 mm. Manufactured from DURAN®, they provide a robust cone interface for building or extending jointed glass apparatus in distillation, extraction and related laboratory set-ups. The 19/26 ground joint aligns with common NS accessory ranges, so the tubes integrate cleanly with matching flasks, adapters and connectors. According to the manufacturer description they are tubes with standard ground joint 19/26 made of DURAN®; the short description further specifies cone geometry and the 130 mm length for predictable handling and fit. Delivered as 10 pc(s) with a pack weight of 0,260 kg, these tubes are from manufacturer Lenz and belong to the glass components range used for distillation and extraction work. Defined joint size, cone form and length support reproducible assemblies in laboratories that rely on NS 19/26 standards and prefer DURAN® tubing for everyday jointed-glass applications.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

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