- How long can the bacteria survive in the vial?
Our range is packaged under inert gas (nitrogen or argon). The lack of oxygen makes the bacteria in remain dormant (sleeping) but always alive. When you need the product, you just have to break the vial and to put the liquid in the water. With the contact of the oxygen, the bacteria awake and start their cleaning work. That is why there is no limit of use the vial.
