Oxygen Absorber Indicators

Each Oxygen Absorber Package includes one Oxygen Indicator which is represented as a small pink dot. The pink oxygen indicator is a visual confirmation that your package contains fresh oxygen absorbers and will do its intended job when used. The colour of the indicator may vary from bright pink to a reddish hue indicating that the package is properly sealed and that there is no oxygen in the package. Once the package is opened and exposed, you will notice the indicator rapidly changing to blue. Please keep in mind that it does not mean your oxygen absorbers are compromised, oxygen absorbers can absorb a large quantity of oxygen and still be effective. The pink indication simply means no oxygen is present in its environment and blue means that oxygen is still present in its environment. Once all oxygen is absorbed from its environment the indicator will regain its pink/reddish hue. This may take up to a day or more.  

This may sometimes be the case when the oxygen absorbers have been recently packed and shipped promptly to its destination and since it takes Indicators over a week to become pink customers may receive indicators of this colour. If the package is not damaged and is still vacuum sealed when you receive it the indicators should start turning pink which could take up to a day or more. You can check the freshness of oxygen absorbers by feeling them. They will feel like fine powder if they are uncompromised which means they are good for use. If they will feel hard and crunchy means they have been exposed and therefore, cannot be used.  

Get everything prepared so you can spend as little time as possible having your oxygen absorbers exposed to air.  It takes about 2 hours in the open air for an Oxygen Absorber to become fully exposed but you should try and get sealing done within 10 minutes. 20 minutes is the maximum amount of time you should have your oxygen absorbers exposed.  The Oxygen Absorber Packs are vacuum sealed so your oxygen absorbers should be fresh to begin with. Fresh oxygen absorbers indicators should be a shade of pink or red, NOT dark blue. Fresh oxygen absorbers have a reddish brown or pink hue indicator. Indicators turn dark blue when oxygen is present. Fresh oxygen absorbers will feel soft, as if to contain powder. When the oxygen absorber is fully exposed and no longer fresh it will feel hard and crunchy. 

You can place unused oxygen absorbers back in the bag they came in and vacuum seal them properly. You can also place unused oxygen absorbers in a mason jar and closed very tightly. If you only have a few oxygen absorbers and a large jar, you can fill the jar with marbles or similar to take up most of the empty space and place your oxygen absorbers in the jar.
