Ageless Eye Oxygen Indicator

The Ageless Eye Oxygen Indicator is an in-package monitor which indicates the presence of oxygen at a glance as the indicator changes from a pink to blue color.

When exposed to oxygen, the Ageless Eye turns from pink to blue or purple, then returns to its original pink color as the oxygen in the sealed package is reduced. The lower the temperature, the slower the color change on the indicator. The color change is reversible, and Ageless Eyes can be reused up to four times.

Ageless Eye comes in a sealed pack of 25 individually sealed units. The tablet reacts immediately in the individual plastic bag surrounding it as soon as it is removed from the outer bag. The small bag surrounding the individual tablet should NOT be opened. Unused Ageless Eye should be stored in an oxygen free environment in a cool (below 15 degrees C) dark place. If the entire pack of 25 is not used, the unused portion should be stored again in a freshly made oxygen free environment consisting of Escal and RP Absorber.

The shelf life of the Ageless Eye should not exceed 6-12 months. This means it should be relied as an initial monitor within the package to confirm oxygen has been depleted, but should not be relied on for long term. Normal air contains 21% oxygen, so when oxygen is removed by a scavenger a slight vacuum will be created in a sealed pouch if most available air was removed before closure. The continued vacuum is an additional confirmation that oxygen is free from the environment.

Manufactured by Mitsubishi Gas Chemical Company in Japan.

In recent years the Ageless Eye has been found to have mixed results for accuracy. It is still a useful and helpful tooll in creating anoxic environments, but should be relied on with caution.
