Description
Hexagonal stopper NS 29/32 is a polypropylene laboratory stopper sized for standard ground joints of NS 29/32. It is intended as a practical closure for matching laboratory glassware such as flasks, adapters and related vessels that use this common European joint size. The hexagonal head supports secure grip and straightforward handling when fitting or removing the stopper during routine work. Made of polypropylene, the stopper offers a lightweight plastic alternative where a glass stopper is not required. Pack size is 100 pc(s), making the item suitable for stocking as a consumable joint closure in teaching, research and quality-control laboratories. These hexagonal stoppers from manufacturer Hecht follow the familiar NS sizing system used throughout laboratory glassware setups, helping ensure dimensional correspondence with NS 29/32 joints. They belong to standard laboratory materials for everyday sealing tasks and support organised inventory of ground-joint accessories without unnecessary complexity in design or specification.

Questions about PP stoppers hexagonal, Size: NS 29/32
What is this article?
PP stoppers hexagonal, Size: NS 29/32 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.
