"GSC International"

Verify gas production in fermentation exercises, gas produced by yeast or other organisms rises into a 5 or 10 ml evolution tube.

For use in the collection and observation of gases produced by fermentation.

Fermentation tubes manufactured from borosilicate glass.

Build compact gas handling setups and guide gases through drying materials in classroom chemistry assemblies.

Outfit multiple stations for gas collection and volume measurement labs.

Let students collect gases and read volume changes during reactions.

Made from high quality borosilicate glass.
