Description
Rubber stopper with top diameter 41,5 mm, bottom diameter 32 mm and height 42,5 mm is a tapered laboratory closure for sealing flasks, bottles and other glassware necks. Made from red natural rubber, it offers a flexible, resilient fit that conforms to round openings and supports secure containment during storage, mixing, sampling or short-term holding of liquids and solids. The conical geometry—wider at the top and narrower at the base—helps seating across a practical range of neck sizes used in chemical, analytical, teaching and general laboratory workflows. Each pack contains 10 pieces with a net weight of 0,655 kg, making restocking of benches and preparation areas straightforward. These stoppers from manufacturer Labbox suit routine sealing tasks where a durable natural-rubber plug is preferred. The solid form supports repeated insertion and removal while maintaining a dependable closure that helps limit evaporation and contamination in everyday use. Clear dimensional marking of the 41,5 mm / 32 mm taper and 42,5 mm height aids quick size matching within multi-format stopper assortments.

Questions about Rubber stopper, solid, Øtop. 41,5 mm, Øbottom 32 mm, h 42,5 mm, 10 pcs
What is this article?
Rubber stopper, solid, Øtop. 41,5 mm, Øbottom 32 mm, h 42,5 mm, 10 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 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.
