Description
Glass stopper for NS 7/16 is a hollow clear-glass stopper designed for tight closure of vessels with a standard ground joint of size NS 7/16. Manufactured in accordance with DIN 12 252, it provides a reliable seal for laboratory glassware used in chemical, analytical, and preparative work. This hollow glass stopper from manufacturer Hirschmann is intended for dense sealing of flasks and similar apparatus where a precise ground-joint fit is required. Supplied in a pack of 10 pieces, each stopper has a net weight of 0,002 kg and is made from unspecified glass in clear form for good visibility of the joint interface. The NS 7/16 joint size matches corresponding laboratory glassware, supporting consistent, leak-resistant closure during storage, reaction, or transport of samples. Clear hollow construction keeps weight low while maintaining the chemical resistance and dimensional accuracy expected of standard ground-joint stoppers in routine laboratory practice.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about GLASS STOPPER NS 7/16
What is this article?
GLASS STOPPER NS 7/16 is the article on this page. Luminix Health distributes Hirschmann 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.
