Airlock - Junior
$5.95Price
An airlock is a device used in fermenting that allows carbon dioxide to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation.
Clean up, and sanitation is easy once the three pieces have been disassembled.
This airlock creates a closed fermentation that allows CO2 to escape from your carboy or bucket but does not allow air or contaminates back into your beer.
