Description
Cork stopper with height 30 mm, top outer diameter 55 mm and bottom outer diameter 50 mm is a conical laboratory stopper manufactured from natural cork. This standard stopper is intended for sealing flasks, bottles and other glassware commonly encountered in chemical, biological and general laboratory work. The tapered conical profile supports progressive insertion and a secure fit in matching neck openings. Dimensions of 30 × 55 × 50 mm (height × top OD × bottom OD) define its geometry for reliable compatibility with corresponding vessels. These cork stoppers from manufacturer IDL GmbH are supplied as 1 piece, suited to individual laboratory requirements. They form part of the established range of cork and norm stoppers used for temporary or longer-term closure of sample containers during experimental procedures, storage or transport. The natural cork material provides the classic compressibility associated with traditional laboratory sealing solutions while remaining fully defined by the stated dimensional and material specifications.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper, H x top Ø x bottom Ø: 30 x 55 x 50 mm, tapered
What is this article?
Cork stopper, H x top Ø x bottom Ø: 30 x 55 x 50 mm, tapered is the article on this page. Luminix Health distributes IDL GmbH 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.
