Works great
I use it on my 1000 ml flask when making starters. Worked perfectly.

Upgrade from tin foil
I have been making yeast starters for over a year and have been using tin foil for the top of my flask. I upgraded to the foam stopper last weekend and man I love these things. I should have spent the pennies a year ago. So much nicer and definately a more sanitary fit in the top of the flask.

Great for starters
This foam stopper is a perfect fit for my 1 liter Erlenmeyer flask. Why waste foil when you can get one of these for less than a buck, and use it again and again?

Great for yeast starters
This stopper is great for for yeast starter flasks. Mine both discolored but a simple wash in sanitizer keeps them in good condition.
