Description
Conical joint stopper NS 14/23 in borosilicate glass 3.3 is a hollow laboratory stopper fitted with a hexagonal grip disc. This precision component seals standard taper joints on flasks, condensers and reaction vessels used throughout chemical and analytical work. The borosilicate glass 3.3 construction provides the dimensional stability and chemical durability expected of high-quality laboratory glassware. Its hollow body keeps overall mass low while the hexagonal grip disc allows secure handling during insertion and removal, even when gloves are worn. Supplied as a single piece from manufacturer Brand, the stopper matches common NS 14/23 ground-joint systems found in distillation, reflux and general synthesis apparatus. Laboratories value the consistent fit and robust build for repeated assembly and disassembly cycles. Net weight is 0,0087 kg, making the stopper convenient to store and deploy in everyday glassware setups that require reliable conical closures.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Conical joint stopper Boro 3.3, NS 14/23, hollow, hexagonal grip
What is this article?
Conical joint stopper Boro 3.3, NS 14/23, hollow, hexagonal grip is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
