Details

Breathable foam stoppers will withstand boiling or autoclaving temperatures, making them ideal for use in preparing a yeast starter. The honeycomb structure of the foam stoppers will act is a filter for any airborne bacteria or wild yeast that might enter the flask. That's important because a lot of air is sucked into the flask while it is cooling. You can also leave the stoppers on the flask instead of a fermentation lock. Some people use foam stoppers to replace fermentation locks in their carboys, too.

The large foam stoppers are 46-60 mm wide and fit our 2000 and 5000 ml borosilicate glass flasks.

It's a foam stopper that fits the 2000 ml flask. There really isn't much more to say. (Posted on 10/22/13)

bad fit for 2000 ml flasks Review by chris
Rating
too big for 2000 ml flasks... it will fit with squeezing, but this causes creases/change in shape in sides of stopper and it doesn't seal the mouth of flask cleanly (Posted on 3/1/12)
