Rings

Cork lab rings are used to support round bottom flasks and protect table surfaces. They are all 30mm thick (height when laying on a surface) and vary by the diameter of the ring and the hole. Used to protect your expensive laboratory glass from breakage. Available in the following sizes: 30mm x...

Material: borosilicate glass Description: Quantity: ~590/lb. L × O.D. × thickness: 6 mm × 6 mm × 1 mm

Viton o-ring is stocked in brown 75 durometer. They are suitable for acids, aliphatic hydrocarbons, oxidizing agents and all petroleum products. Viton has a low compression set and high temperature resistance. Viton is especially good for vacuum service and low gas permeability and has a useful...

O-Rings in a variety of sizes and materials. Please see o-ring materials chemical compatibility here: http://www.aceglass.com/downloads/eccc.pdf

Fabricated from Borosilicate glass. Wall weight on 5mm size is approximately 0.8, other sizes have wall weight of approximately 1.0/mm.

For supporting round-bottom flasks, dishes, etc. All rings are 30 mm high with inside edge beveled

Made of fine particle compressed cork, these rings are designed to support round bottom flasks, beakers, dishes and more. Cork is naturally elastic with very low thermal and electrical conductivity properties. Small cork stand has a diameter of 100mm and holds 250ml to 2000ml round bottom flasks....

Laboratory cork ring stand for round-bottom flask.

Rings are made of borosilicate glass and sold in one pound packages.

One of the most thermally stable elastomeric materials available, Perfluoro is a family of perfluoroelastomer compounds designed to provide superior chemical resistance, and they offer a cost savings over similar o-rings such as Kalrez® 4079 and Chemraz®. Perfluoro o-rings are stocked in...
