Heat resistance and safe support for glassware.

• Naturally elastic
• Low thermal properties

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 100 mm and holds 250 to 2000 ml round bottom flasks. Large cork stand has a diameter of 120 mm and holds 500 to 3000 ml round bottom flasks.
