Beschrijving
Rubber stopper with top diameter 13 mm, bottom diameter 9 mm and height 15,5 mm is a compact tapered laboratory closure for small-neck tubes, vials and fine glassware. Fabricated from red natural rubber, it provides a flexible, resilient seal that conforms to narrow openings and supports secure containment of small liquid or solid samples during storage, transfer or short-term holding. The conical shape—13 mm at the top tapering to 9 mm at the base—fits many small laboratory vessels used in analytical, educational and general bench work. Each unit is supplied in a pack of 25 pieces with a net weight of 0,055 kg, convenient for high-turnover stations and multi-user labs. These stoppers from manufacturer Labbox address routine sealing needs where a durable natural-rubber plug in a small format is required. The solid body withstands repeated insertion and removal while maintaining a reliable closure that helps limit evaporation and contamination. Clearly stated dimensions of 13 mm / 9 mm and 15,5 mm height simplify matching to the correct neck size within a broader stopper range.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rubber stopper, solid, Øtop. 13 mm, Øbottom 9 mm, h 15,5 mm, 25 pcs
What is this article?
Rubber stopper, solid, Øtop. 13 mm, Øbottom 9 mm, h 15,5 mm, 25 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labmateriaal.
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.
