Temperature limits:
This indicator has 2 time-temperature sensitive indicators, which irreversibly change color at a constant rate at the following ambient temperatures:
– +10°C
– +34°C
Time/temperature function:
Indicators will respond to an overshoot as follows:
– +10°C indicator: 14 days for a fully colored window at +12°C. The +10°C indicator strip is placed behind three equally sized windows, named “A,” “B” and “C,” so users can clearly distinguish which stage of the process this vaccine is at.
– +34°C indicator: 3 hours for a fully colored window at 37°C.
The +34°C indicator is placed behind the window named “D,” so users can clearly observe the discoloration once it has been above 34°C.
