Description
Silicone stopper with a top diameter of 60 mm, a bottom diameter of 50 mm and a height of 45 mm is a tapered laboratory closure for sealing flasks, bottles and other open vessels in routine chemical and analytical work. Manufactured from silicone in a brown colour, the stopper combines elasticity with a secure fit across the stated dimensions, supporting reliable closure where glass or plastic necks require a soft, conforming seal. The material remains serviceable across a wide working range from −70 °C to 200 °C, making it suitable for cold-storage setups as well as moderately heated apparatus when thermal cycling is part of the workflow. Supplied in a practical pack of 10 pieces from manufacturer Labbox, the stoppers are convenient for stocking multiple benches or shared preparation areas. With a net weight of 0,078 kg per pack, they are lightweight yet robust enough for everyday handling. Typical uses include temporary sealing during sample preparation, solvent handling and general laboratory organisation where a reusable silicone plug is preferred over disposable alternatives. The conical profile aids insertion and removal while helping maintain contact along the vessel neck.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Silicone stopper, solid, Øtop 60mm, Øbottom 50 mm, h 45 mm, 10 pcs
What is this article?
Silicone stopper, solid, Øtop 60mm, Øbottom 50 mm, h 45 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.
