Description
Hexagonal stopper, polypropylene, size NS 10/19 is a laboratory closure for standard ground-joint glassware. The hexagonal head allows firm finger grip and controlled insertion or removal from matching NS sockets, supporting secure sealing of flasks, adapters, and other jointed apparatus during storage, transport, or short-term holding of samples and reagents. Manufactured in polypropylene, the stopper offers a lightweight, durable alternative to glass stoppers for many routine laboratory applications where chemical compatibility with PP is acceptable. This hexagonal stopper from manufacturer Hecht is sized specifically for NS 10/19 joints, helping maintain a consistent fit within common European joint systems. It is well suited to teaching laboratories, quality-control benches, and research setups that require reliable, easy-to-handle closures in bulk. Supplied in a pack of 100 pieces, the stoppers support efficient stocking of multi-user labs and reduce downtime when replacements are needed across parallel experiments or student practicals.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about PP stoppers hexagonal, Size: NS 10/19
What is this article?
PP stoppers hexagonal, Size: NS 10/19 is the article on this page. Luminix Health distributes Hecht 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.
