Ageless Eye® Oxygen Indicators
Ageless Eye Oxygen Indicators are small, individually packaged
tablets which indicate the presence/absence of oxygen by colour
change. Ageless® Eye indicators may be included in anxoic packages
to indicate the effective absorbtion of all oxygen, and to warn
of a breakdown in the oxygen barrier. Ageless Eyes® indicate the
lack of oxygen (<.01%) by turning pink. At an oxygen level of .5%
or more, the tablet turns blue. The presence of oxygen will be indicated
in five minutes or less, while the change from blue to pink may
take three hours or more.
When refrigerated and maintained in an oxygen-free state the manufacturer
suggests that six months is the indicators maximum shelf life. Based
on our experience with the Eyes, we advise caution when planning
on using them in a laboratory or long-term applications, as these
indicators may become unreliable after only a few "cycles" from
low to high oxygen levels.
Ageless Eyes® are only available as a special order item. They
are sold ONLY in carton quantities (500 pieces), and are only sold
to commercial customers currently using Ageless.
