Foam Stopper 1 3/4"

Erlenmeyer flask sized foam stopper. Used with 1000ml and 2000ml sizes. Regicell's products have been specifically developed to meet the exacting requirements of quality filtration foam. Regicell foams are thermally reticulated polyester products.

These foam stoppers are heat resistant and can be used while boiling or auto-claving your flask. Due to the material allowing oxygen to pass through it, it is ideal for yeast starters as the material will keep contaminants out of your starter while providing the oxygen that is crucial to ensure healthy cell growth.
