AIR STOPPER FOR FERMENTATION M

MINI plastic tube - made of very high quality PVC plastic, characterized by high durability. It has two bubbles. Fits the hole in the rubber balloon plugs.

Usage:
The fermentation tube, filled with water, is used in the fermentation process to protect the contents of the kit from oxygenation and at the same time allows for the regular release of the carbon dioxide formed.
Thanks to the shifting water column, we can observe the changing intensity of the fermentation process from the turbulent stage (intense boiling) to the stationary stage. It is natural for water to evaporate, so do not forget to top up the level in the tube. If you do not do this, the liquid can become saturated with oxygen too intensively and, consequently, the ethanol formed can be oxidized to acetic acid. This unfavorable process can also be caused by fruit flies if they enter the vessel.
