Description
Cork stopper conical with height 32 mm, top diameter 23 mm and bottom diameter 19 mm functions as a laboratory closure element produced from natural cork. The extended height combined with the tapered diameters creates a stable sealing surface for larger or deeper vessel necks. Dimensional data expressed as height by upper outer diameter by lower outer diameter enable precise selection against standard laboratory glassware. Offered as a single unit, the stopper is immediately available for sealing flasks, bottles or similar containers during preparation, reaction or storage steps. Natural cork supplies the compressibility essential for a friction-based seal. This conical cork stopper from manufacturer IDL GmbH is included in the norm-stopper and cork-stopper product family serving research and routine laboratory needs. The 32 × 23 × 19 mm specification addresses applications requiring a somewhat taller profile while retaining the familiar conical insertion characteristics. Simple manual placement without tools supports efficient workflow in environments where cork-compatible media are handled.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork stopper, H x top Ø x bottom Ø: 32 x 23 x 19 mm, tapered
What is this article?
Cork stopper, H x top Ø x bottom Ø: 32 x 23 x 19 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.
