In the world of yeast starters, aeration is key to creating a strong and healthy foundation for your brewing endeavors. To achieve this, a stir plate is a crucial tool, providing continuous aeration to promote optimal yeast growth. However, an essential accessory often overlooked is the humble foam stopper. Our Autoclavable Foam Stopper is designed specifically for use with Erlenmeyer flasks, allowing for free airflow while keeping unwanted contaminants at bay.

This ingenious device is compatible with flasks or vessels featuring an inner diameter opening of 35-45mm (1-3/8" - 1-3/4"), making it an essential addition to your brewing arsenal. The reusable foam stopper is constructed to resist a wide range of chemicals, including alcohols, bases, esters, and dilute acids, ensuring it stands up to the demands of your brewing process. What's more, it can withstand autoclaving up to 249°F (121°C), providing a sterile environment for your yeast starter to thrive.

The benefits of using a foam stopper are twofold. Firstly, it allows for the free flow of air into your flask, providing the necessary oxygen for yeast growth and multiplication. Secondly, it acts as a barrier, preventing unwanted contaminants, such as bacteria and wild yeast, from entering your flask and spoiling your starter. The result is a strong, healthy yeast starter that will help your brews reach their full potential.

Cleaning and maintenance are also made easy with our foam stopper. A quick spray down with sanitizer is all that's required to keep your stopper in prime condition, ready for its next use. This convenience, combined with its durability and reusability, makes our Autoclavable Foam Stopper an essential tool for any serious brewer.
