Glass airlock for fermentation Ø8.5mm

Glass airlock filled with water is used during the fermentation process to protect the fermentable wort against oxygenation and at the same time ensures the regular release of carbon dioxide generated during the fermentation process.

Thanks to the water in the airlock, we can observe the variable intensity of the fermentation process from the turbulent stage (intense bubbling) to the stable stage.

Remember that water evaporates, so do not forget to top up the water level in the airlock.

In the event that there are limited possibilities to control the water level in the hydraulic seal, it can be filled with a less volatile oily liquid.

Has a certificate for contact with food.
