Foam Stopper (Autoclavable), for erlenmeyer flasks


In stock (available)

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 contaminants 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″).

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