Description
Cork stopper with top diameter 60 mm, bottom diameter 55 mm and length 30 mm is a tapered natural cork laboratory stopper intended for sealing flasks, bottles and comparable vessels. Its conical profile reduces from 60 mm at the top to 55 mm at the base across a 30 mm length, giving a controlled fit in suitably sized openings. Fabricated from cork, the stopper retains the compressibility associated with natural cork closures in laboratory practice. Net weight is 0,02 kg per piece, supplied in a pack of 10 pc(s) from manufacturer Witeg. The product originates from Portugal. It is appropriate for everyday laboratory sealing tasks that call for a short cork stopper with these stated diameters. The taper assists insertion and removal while preserving contact on the sealing face. Explicit upper and lower diameters support straightforward selection against vessel neck dimensions. This size forms part of the standard cork stopper assortment for general laboratory use and is chosen by measured opening rather than ground-joint designation.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper Ø top 60mm Ø bottom 55mm length 30mm
What is this article?
Cork stopper Ø top 60mm Ø bottom 55mm length 30mm is the article on this page. Luminix Health distributes Witeg 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.
