Description
Cork stopper with a top diameter of 100 mm, a bottom diameter of 95 mm and a length of 30 mm is a classic tapered laboratory closure for vessels and flasks that require a natural, compressible seal. Made from cork, the stopper offers a snug fit that adapts to the neck geometry while remaining easy to insert and remove during routine handling. The slight taper between the upper and lower diameters supports reliable seating in openings of matching size, making it suitable for general laboratory, teaching and preparative work where glassware must be closed quickly without specialised fittings. Supplied in a practical pack of five pieces and weighing 0,048 kg net per unit, these stoppers from manufacturer Witeg are a straightforward consumable for everyday sealing tasks. Categories such as standard stoppers and cork stoppers underline their role alongside rubber, silicone and cellulose alternatives when a traditional cork interface is preferred. Dimensions are clearly defined for straightforward selection against vessel openings.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper Ø top 100mm Ø bottom 95mm length 30mm
What is this article?
Cork stopper Ø top 100mm Ø bottom 95mm 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.
