Description
Ground joint stopper, hexagonal, NS 14/23 is a conical laboratory stopper manufactured from borosilicate glass LBG 3.3 for standard ground-joint glassware. The hexagonal head provides a secure grip for insertion and removal, while the precision-ground conical joint matches NS 14/23 apparatus commonly used in synthesis, distillation, and general wet-chemistry setups. LBG 3.3 borosilicate glass offers the thermal and chemical durability expected in routine laboratory service. This single-piece stopper from manufacturer Labbox is intended for sealing flasks, adapters, and other NS 14/23 components without additional fittings. Compact and robust, it supports reproducible joint closure in teaching, research, and quality-control laboratories. Pack size is 1 pc(s) with a net weight of 0,009 kg. Suitable wherever a durable hexagonal ground joint stopper in the 14/23 size is required for conical standard joints.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Hollow stopper, hexagonal head, LBG 3.3, 14/23
What is this article?
Hollow stopper, hexagonal head, LBG 3.3, 14/23 is the article on this page. Luminix Health distributes Labbox 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.
