Description
Silicone stopper 75,5 - 64,5 mm Ø, 55 mm h is a tapered laboratory stopper made of silicone for sealing flasks, bottles and other vessels in scientific and medical laboratory work. It presents an upper diameter of 75,5 mm that narrows to a lower diameter of 64,5 mm over a height of 55 mm, forming a conical profile that seats in matching openings. Supplied as a single piece, the stopper belongs to the silicone stopper group within the wider assortment of laboratory stoppers that also covers norm stoppers, cork stoppers, rubber stoppers and cellulose stoppers. This item from manufacturer Hecht is intended for routine closure tasks during sample handling, storage or experimental procedures where a solid silicone seal is required. The stated diameters and height define its fit for correspondingly sized necks. As a basic laboratory accessory it supports everyday sealing needs without further modification, and the single-piece unit quantity permits straightforward ordering for individual replacement or small-scale use in research and analytical settings.

Questions about Silicone stoppers mm 75,5 - 64,5 Ø 55 h
What is this article?
Silicone stoppers mm 75,5 - 64,5 Ø 55 h 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.
