Description
Conical cork stopper with height 22 mm, top diameter 13 mm and bottom diameter 10 mm serves as a practical laboratory sealing component for glassware and vessels. The tapered form allows progressive insertion into matching neck openings, creating a secure yet removable closure suitable for flasks, bottles and tubes. Natural cork material supplies the elasticity and compressibility needed for reliable fitting across minor dimensional variations while remaining easy to handle. This stopper supports routine laboratory tasks such as sample containment, short-term storage, reaction setups and protection against evaporation or contamination in chemical, biological and educational environments. Pack size is 1 pc, enabling convenient individual use or replacement. Dimensions of 22 mm height with the 13 mm to 10 mm taper ensure adequate grip length and sealing depth for stable positioning during experiments or transport. Produced by manufacturer IDL GmbH, the item belongs to the established range of standard cork stoppers employed in scientific workflows. Its straightforward conical geometry facilitates quick assembly of glassware without specialised tools and integrates smoothly into distillation, titration or general apparatus configurations where temporary sealing is required.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper, H x top Ø x bottom Ø: 22 x 13 x 10 mm, tapered
What is this article?
Cork stopper, H x top Ø x bottom Ø: 22 x 13 x 10 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.
