Foam Stopper (Autoclavable)

Please select from the following option(s) to see pricing and availability.

Use this foam stopper with your Erelenmeyer flask when making a yeast starter. Aeration is an important aspect of making a strong, healthy starter. This is why we recommend using a stir plate, which provides continuous aeration. This foam stopper will allow air to flow freely into your flask while keeping pesky bugs and other contaminents out. A quick spray down with sanitizer is all you need. Suitable for flasks or other vessels with an inner diameter opening of 35-45mm (1-3/8" - 1-3/4").

  • Reusable
  • Resists alcohols, bases, esters, and dilute acids
  • Autoclavable up to 249°F (121°C).
