Description
Glass-stoppers, solid, DURAN® are precision laboratory stoppers designed for reliable sealing of glassware with standard ground joints. These solid stoppers feature an octagonal head and a standard ground joint size of 19/26, supporting secure closure of flasks, bottles and reaction vessels in everyday laboratory work. Manufactured from DURAN® borosilicate glass, they offer the chemical resistance and dimensional stability expected of quality lab glassware for routine handling of solvents, reagents and process samples. The octagonal form allows a firm grip when inserting or removing the stopper, which is useful during setup, sampling and cleaning cycles. Supplied in a practical pack of 10 pieces with a total weight of 0,360 kg, the set suits stock replenishment in teaching labs, analytical suites and research facilities. These stoppers from manufacturer Lenz fit standard taper joints of the stated size and integrate smoothly into existing glassware assemblies without special adapters. They belong to the stoppers-with-standard-taper category of laboratory glass consumables and support consistent joint sealing across repeated use. Ideal for general chemistry, preparative work and vessel storage where a solid DURAN® stopper with NS 19/26 geometry is required.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Glass-stoppers, solid, DURAN®, octagonal, standard ground joint 19/26
What is this article?
Glass-stoppers, solid, DURAN®, octagonal, standard ground joint 19/26 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.
