Bubbler Airlock

This simple and strong airlock is the only one we use ourselves.

It is half filled with a liquid to form a barrier for the brew against the exterior yet allow passage for released CO2.

May be filled with water or a weak solution of Sodium or Potassium Metabisulphite or a high alcohol drink such as Vodka.

External dim of stalk: approx.10mm
