Description
Pressed cork laboratory ring 140 x 90 x 30 mm is a laboratory support accessory formed from natural cork into a stable ring profile. It presents an outer diameter of 140 mm, an inner opening of 90 mm and a height of 30 mm, allowing secure placement of round-bottom flasks and similar glassware on the bench. The pressed cork construction supplies a resilient, non-scratch contact surface together with inherent thermal insulation useful during routine heating or cooling steps. Packaged as 1 pc, the ring is immediately ready for chemistry, biology or general laboratory workflows. Physical characteristics of the cork material include moderate compressibility and chemical inertness that help maintain vessel position without metallic contact. This laboratory ring pressed cork item from manufacturer IDL GmbH integrates easily into standard lab setups where lightweight, natural supports are preferred. Dimensions of 140 x 90 x 30 mm ensure compatibility with many common flask sizes, supporting safe handling during distillations, reactions or temporary storage. Technicians value the simple geometry for organising apparatus in teaching, research and quality-control environments that require reliable cork-based holders.

Questions about Cork flask support ring, O.D. x I.D. x Height: 140 x 90 x 30 mm
What is this article?
Cork flask support ring, O.D. x I.D. x Height: 140 x 90 x 30 mm 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.
