Description
Solid glass stoppers DURAN® are octagonal laboratory stoppers with standard ground joint 14/23 for sealing flasks, bottles and other ground-joint glassware. The solid DURAN® construction provides a rigid, chemically resistant closure that mates with matching NS 14/23 sockets used throughout European laboratory glassware systems. An octagonal head improves grip when inserting or removing the stopper during routine handling. These stoppers from manufacturer Lenz are packed as 10 pc(s) with a total weight of 0,250 kg, supporting multi-station benches and shared glassware stores. Solid ground-joint stoppers are applied wherever a reusable glass seal is preferred over plastic or rubber alternatives, including reaction flasks, storage vessels and apparatus assemblies that already use the 14/23 joint size. DURAN® glass maintains dimensional stability of the ground surface under normal laboratory conditions. The pack of ten allows consistent replacement of worn or missing stoppers without mixing joint sizes. Suitable for teaching, research and quality-control laboratories that standardise on NS 14/23 connections.

Questions about Glass-stoppers, solid, DURAN®, octagonal, standard ground joint 14/23
What is this article?
Glass-stoppers, solid, DURAN®, octagonal, standard ground joint 14/23 is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
