Description
Cork stopper with top diameter 65 mm, bottom diameter 60 mm and length 30 mm is a tapered natural cork laboratory stopper for closing flasks, bottles and similar containers. The conical body narrows from 65 mm at the upper face to 60 mm at the lower face over a length of 30 mm, enabling a defined fit in matching openings. Produced from cork, it offers the compressibility characteristic of natural cork stoppers in scientific settings. Each unit weighs 0,02 kg net and is supplied in a pack of 10 pc(s) from manufacturer Witeg. Country of origin is Portugal. The stopper is suited to routine laboratory sealing where a short cork closure of these diameters is specified. Tapered geometry supports insertion and withdrawal while maintaining sealing contact. Clearly stated top and bottom diameters ease matching to vessel necks. This format belongs to the standard cork stopper range for general laboratory applications and is selected according to measured opening size rather than nominal joint codes.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper Ø top 65mm Ø bottom 60mm length 30mm
What is this article?
Cork stopper Ø top 65mm Ø bottom 60mm 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.
