This foam stopper fits in our 1000mL and some 2000mL Erlenmeyer flasks. Please double check the size of your 2L as all flasks are not created equal. Instead of using tin foil for your stopper you can use this breathable foam stopper.

Made by Regicell, this product line has been specifically developed to meet the exacting requirements of quality filtration foam. Regicell foams are thermally reticulated polyester products.
