Description
Standard ground glass joint stoppers in polyethylene (PE) for NS 7/16 joints provide a practical closure for laboratory glassware with standard taper connections. Each stopper is fitted with a blue insert for quick visual size identification at the bench, reducing mix-ups when several joint sizes are in use. The PE body offers a lightweight, chemically resistant seal for flasks, cylinders and other vessels equipped with NS 7/16 ground joints during storage, transport or short-term holding of samples and reagents. Packaged as 10 pieces with a pack weight of 0,010 kg, the set supports multi-station laboratories and teaching environments that need spare stoppers on hand. These stoppers from manufacturer DWK Life Sciences belong to the standard taper stopper range used across chemical, analytical and life-science labs. Colour-coded blue inserts help staff match the correct NS 7/16 size quickly, while the polyethylene construction is suitable for everyday closure tasks where glass stoppers are not required. Ideal for organising jointed glassware inventories and maintaining secure temporary seals.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Standard ground glass joint stoppers, PE, NS 7/16, insert blue, 10 unit(s)
What is this article?
Standard ground glass joint stoppers, PE, NS 7/16, insert blue, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
