Description
neoChoice stoppers 20 mm in grey butyl are hollow stoppers designed for use with ND20 crimp closures in routine laboratory sealing work. With a 20 mm diameter, they provide a practical elastomeric seal for vials and bottles that are finished with standard ND20 crimp systems, supporting sample containment during handling, storage preparation, and transfer steps.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.
Supplied as a pack of 100 pieces, the grey butyl construction is suited to everyday laboratory workflows where reliable stopper geometry and consistent fit matter. These neoChoice hollow stoppers from manufacturer neolab - Labor integrate cleanly into crimp-seal setups and are a straightforward consumable for chromatography sample preparation areas, general analytical labs, and quality-control benches that rely on ND20 closures. The butyl material offers the flexibility expected of laboratory stoppers while the hollow design supports mounting under aluminium crimp caps. Choose this pack when you need uniform 20 mm grey butyl stoppers ready for ND20 crimp applications without unnecessary complexity in specification.

Questions about neoChoice Stopfen 20 mm, Butyl grau, 100 Stck./Pack
What is this article?
neoChoice Stopfen 20 mm, Butyl grau, 100 Stck./Pack is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
