One piece 2 Chamber airlock that features a smaller chamber so you can closely observe the CO2 rising and with that, the rate of fermentation. Fill the airlock with water and insert into a drilled stopper to vent gases during fermentation.
Airlocks enable CO2 to be released during fermentation, but it traps oxygen from entering the fermenter and harming your beer or wine. Choose between the Bubbler Airlock and the Three-Piece Airlock. Compatible with all our drilled stoppers.
