Description
Tubes with standard ground joint 45/40 are laboratory glass tubes fitted with sockets that carry a standard ground glass joint of size 45/40 and a length of 145 mm. Manufactured from DURAN®, they provide robust connection pieces for larger modular glass apparatus used in distillation, extraction and related laboratory assemblies. The 45/40 ground joint supports a secure, interchangeable fit with matching cones and complementary ground-joint components, which is valuable when apparatus scale or throughput calls for wider joint geometry. These tubes form part of the glass-component range employed wherever standardised joints simplify setup changes and improve compatibility across multi-piece systems. Offered in packs of 10 pc(s) by manufacturer Lenz, they are practical for laboratories that stock larger joint sizes for teaching, preparative work or routine operations. With a pack weight of 1,200 kg, the set remains manageable for storage and handling within existing DURAN® glassware inventories. They are appropriate whenever a socket connection in the 45/40 standard is needed without extra adapters.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Tubes with standard ground joint Sockets with ground glass joint, 45/40, 145 mm
What is this article?
Tubes with standard ground joint Sockets with ground glass joint, 45/40, 145 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.
