Beschreibung
Rubber stopper without bore 22 x 17 x 25 mm is a solid unbored laboratory stopper manufactured from rubber. It features a top diameter of 22 mm, a bottom diameter of 17 mm and a height of 25 mm, giving a gently tapered profile that seats securely in matching vessel necks. The absence of any pre-drilled bore makes the stopper ideal for complete closure of flasks, bottles and other glassware where an uninterrupted seal is required. Material elasticity of the rubber ensures reliable contact with glass or plastic surfaces under normal laboratory conditions. This stopper is supplied as a single piece and originates from manufacturer Hecht. It belongs to the standard range of norm rubber stoppers used throughout chemical, analytical and general laboratory work for temporary or longer-term containment of liquids, powders or reaction mixtures. Precise dimensional control of the 22 x 17 x 25 mm format supports consistent fit across common neck sizes, simplifying selection and replacement. The solid construction avoids leakage paths associated with bored variants and allows straightforward insertion and removal by hand. Overall the stopper provides a practical, reusable sealing solution for everyday scientific glassware handling.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rubber stoppers without bore Ø mm H 22 x 17 x 25
What is this article?
Rubber stoppers without bore Ø mm H 22 x 17 x 25 is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Laborbedarf.
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.
