Description
Glass stopper for NS 19/26, brown glass is a ground-joint laboratory stopper designed for the tight sealing of vessels equipped with an NS 19/26 standard taper. Fabricated in brown glass and conforming to DIN 12 252, it offers an interchangeable conical joint closure for flasks, reaction vessels and storage glassware that specify this larger common joint size. Brown glass construction aligns with light-attenuating laboratory glassware lines. The product is offered in a pack of 10 pc(s), supporting efficient replacement and multi-vessel setups. Each stopper has a net weight of 0,013 kg and a gross weight of 0,016 kg. These NS 19/26 brown glass stoppers from manufacturer Hirschmann are intended for routine sealing duties in chemical synthesis, sample handling and general laboratory operations where a solid glass plug is preferred. The NS 19/26 joint is widely used on medium-capacity European glassware, and a DIN-conform stopper helps ensure reliable fit and interchangeability with compatible ground-joint apparatus. It provides a dense, reusable seal for vessels that call for a classic brown glass stopper at this taper.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about GLASSTOPPER F. NS 19/26, AMBER GLASS
What is this article?
GLASSTOPPER F. NS 19/26, AMBER GLASS 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.
