Fill the Bubbler Airlock with water and insert in drilled stopper or bung to vent gases during fermentation.
"Bubbler" style airlock makes a gratifying "bloop" noise during active fermentation. It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.
To use: Insert assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. The airlock cap should always stay on top when in use; it has several small holes in it that allow gas to escape but prevent the water inside from quickly spilling out if tipped or jostled.
It's simple and to the point, and works well.
Purchased it to ferment my #SummerSqueezeLemonShandy extract kit. It worked perfectly, with no overflows or leakage problems.
It also withstood my babygirl's extreme biting and tossing, that's why I'm ranking it as bulletproof jejeje.
Worked very well with all the fermenters I have bought from Northern Brewers!
