Description
Hexagonal stopper NS 34/35 is a polypropylene laboratory stopper matched to standard ground joints of size NS 34/35. It serves as a practical closure for flasks, adapters and other laboratory vessels equipped with this European joint format. The hexagonal head allows a firm grip for fitting and removal during daily laboratory handling. Constructed from polypropylene, the stopper provides a plastic option for applications where glass stoppers are not needed. Supplied in a pack of 100 pc(s), it is convenient for laboratories that maintain bulk stocks of ground-joint consumables. These hexagonal stoppers from manufacturer Hecht align with the established NS sizing convention used across laboratory glassware, supporting dimensional compatibility with NS 34/35 joints. They form part of standard laboratory materials for routine sealing tasks in research, education and analytical environments, offering a simple, consistent accessory for organised glassware setups without added complexity in form or specification.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about PP stoppers hexagonal, Size: NS 34/35
What is this article?
PP stoppers hexagonal, Size: NS 34/35 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.
