Porta Stream cartridges include pre-mixed EyeSaline solutions and water additives
- The EyeSaline solutions can be used directly from the container. These solutions are pre-mixed so no mixing or measuring is required. This saline solution is preserved, buffered and pH-balanced.
- The water additive can be mixed with clean, potable water (10:1 ratio). One bottle is suitable for 53-60 L (14-16 gallons). Unopened bottles have a 30 month shelf life.
