Also referred to as a bubbler, fermentation lock, or brewing air lock, it enables CO2 to be released during fermentation, while preventing oxygen and bacteria from entering the fermenter.
Easy to use, the airlock securely protects your ferments from contamination.
To use the fermentation lock, simply fill with water or alcohol up to the "Fill line" level and insert it into the drilled lid of your fermentation container.
The three pieces of this airlock can be easily disassembled and cleaned.
I started with these simple fermentation airlocks and they work great at an excellent price point.
