Symbiota One-way Airlock Lid

Symbiota's one-way airlock fermentation lids are ideally suited to mason jars and are secured with a metal/stainless steel ring (sold separately).

This one-way airlock lid allows for carbon dioxide to escape while inhibiting oxygen from entering. This creates the ideal environment for fermentation, especially quick ferments such as vege mixes.

Dimensions: The Symbiota One-way airlock fermentation lid is 82mm in diameter.

Symbiota One-way fermentation airlock lids are sold individually and colours will vary depending on current stock.
