SKU: SENIOR_AIRLOCK
Senior Airlock - three piece airlock designed to be easy to clean. This unit has a main body, which is used to house a small amount of liquid. There is a floating cap which sits over the hose in the middle of the main body. Finally there is a lid which holds the floating cap in place and creates the bubbling action.
Has a slightly larger external diameter fitting than the standard Vintage S-shaped airlocks, but is still compatible with standard fermenter grommets and bored bungs.

Questions & answers
If my airlock stops bubbling, does that mean fermentation has finished?
No. Bubbles show gas escaping through the airlock; they are not a reliable test of whether fermentation has finished - the last part of fermentation can take longer and won't produce much co2 that a small leak in the fermenter could release. Use a hydrometer and compare specific-gravity readings a few days apart. A falling reading shows fermentation is continuing. Follow your recipe’s expected final-gravity and wait for the gravity reading to stabilize over a few days instead of bottling just because the airlock is quiet.
