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.
I bought two of these to start brewing ginger beer. They arrived on time and not broken. They did what they were supposed to.
I can’t really review this because it is a gift. I know my niece & husband will love it though.
This does the job very well. I like the red cap as it is easier to locate in a bucket filled with sanitizer suds.
Nothing to say other than an airlock keeps things out as the fermentation lets CO2 out of the fermenter.
