Classical water seal with red plastic cap , round model . (height 16 cm diameter 10 mm). By filling out the airlock with water it works as a kind of trap and close the liquid from the outside air. Can no bacteria from outside to inside , but the carbon dioxide formed during fermentation will be able There by the overpressure through the airlock . The snake model is the cheapest but let difficult than the cylindrical models. Purify themselves
Info : By entering the airlock with water, it acts as a kind of siphon and close the wine or beer from the outside . There may be no bacteria from the outside to the inside , but the carbon dioxide formed during fermentation will escape the pressure through the airlock .
