Description
Hexagonal stopper, polypropylene, size NS 14/23 is a laboratory closure for standard ground-glass joints of the NS 14/23 format. The stopper is made from polypropylene and features a hexagonal head that aids grip during insertion and removal from conical joints. It is supplied in packs of 100 pieces, making it practical for laboratories that maintain multiple setups or teaching stations. This item from manufacturer Hecht belongs to everyday labware used to close flasks, adapters and other glass apparatus fitted with NS 14/23 joints. Polypropylene stoppers offer a lightweight alternative to glass stoppers for routine sealing tasks in chemical, analytical and educational laboratories. The defined NS 14/23 size supports dimensional compatibility with corresponding ground joints, helping achieve a secure fit for short-term holding or handling of samples and process mixtures. The hexagonal profile allows controlled turning by hand without additional tools. As a consumable laboratory accessory, the stopper helps keep open necks covered during preparation, transfer or temporary holding steps. Consistent sizing across the pack supports standardised glassware inventories in research, quality control and training environments where NS 14/23 connections are commonly used.

Questions about PP stoppers hexagonal, Size: NS 14/23
What is this article?
PP stoppers hexagonal, Size: NS 14/23 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.
