Description
Cork ring 140 x 90 mm is a laboratory support ring sized 140 x 90 mm with a height of 30 mm, intended for stable resting of larger round-bottom flasks and similar curved glassware. The cork form creates a simple, non-slip seat that helps keep vessels secure during temporary storage, cooling or routine handling without clamps. Net weight is 0,056 kg, so the ring stays manageable and easy to position on the bench. Supplied as 1 pc, this cork ring from manufacturer Usbeck supports everyday chemistry, teaching and research activities. Its practical footprint allows straightforward storage with other laboratory utensils, while the natural cork surface ensures gentle contact with glass. Suitable for general laboratory use wherever a reliable low-profile base is needed for flasks of this size class, the ring delivers consistent dimensions and fits readily into standard bench and preparation workflows.

Questions about Cork Ring 140 X 90 mm
What is this article?
Cork Ring 140 X 90 mm is the article on this page. Luminix Health distributes Usbeck 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.
