Description
Ground joint stopper, PP, NS 60/46 is a polypropylene laboratory stopper for standard ground joints of size NS 60/46. The polypropylene (PP) material provides a durable, lightweight seal for flasks, bottles and other glassware fitted with matching NS 60/46 necks, supporting secure closure during storage, transport or intermediate process steps. Chemical resistance typical of PP makes the stopper suitable for many aqueous solutions and common laboratory media encountered in routine analytical and preparative work. Offered by manufacturer Vitlab, the stoppers arrive as a pack of 10 pieces, which is practical for teaching laboratories, research groups and industrial quality-control benches that maintain multiple ground-joint assemblies. Compared with glass stoppers, the plastic construction reduces breakage risk and simplifies handling when frequent opening and closing is required. The standardised NS 60/46 joint geometry ensures interchangeability with European laboratory glassware of the same designation. Clear joint-size identification helps avoid mismatches during assembly. These stoppers serve as sealing accessories for compatible ground-joint apparatus.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard joint stopper, PP, NS 60/46
What is this article?
Standard joint stopper, PP, NS 60/46 is the article on this page. Luminix Health distributes Vitlab 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.
