3 piece bubbler

The 3-piece aseptic airlock, also called a "barboteur" or "air lock," is a simple and easy-to-use tool during fermentation. It is designed to be inserted into a stopper or a drilled bung, creating a closed fermentation environment allowing CO2 to escape silently while preventing oxygen from entering.

To use the 3-piece aseptic airlock, simply fill it with water or sanitizer up to the fill line and insert it into your stopper or bung. The three-piece design allows for easy cleaning and sanitizing and is compatible with all drilled stoppers.
