Description
Rubber stopper without bore H 59,5 x 50,5 x 45 mm is a solid laboratory stopper intended for sealing flasks, bottles and other vessels without any pre-drilled opening. With a height of 59,5 mm and diameters of 50,5 mm and 45 mm, the tapered profile accommodates a range of standard neck sizes found in everyday glassware. Made from rubber, it combines elasticity with mechanical resilience for repeated insertion and removal while maintaining a secure closure. This single-piece stopper from manufacturer Hecht is well suited to chemistry, biology and analytical laboratories where complete sealing is required for sample storage, evaporation control or temporary containment during mixing. The absence of a bore leaves the option for custom drilling when needed or permits use as a full plug. Its straightforward design supports routine workflows in teaching labs, research facilities and quality-control environments handling aqueous media or mild reagents, providing a practical sealing solution that fits common laboratory vessels.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Rubber stoppers without bore Ø mm H 59,5 x 50,5 x 45
What is this article?
Rubber stoppers without bore Ø mm H 59,5 x 50,5 x 45 is the article on this page. Luminix Health distributes Hecht 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.
