TimestripPlus DUO with 2 sensitive time-temperature indicators with irreversible color function.
TimestripPlus DUO has 2 time-temperature sensitive indicators, which irreversibly change color at a constant rate at the following ambient temperatures:
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.
Vaccine temperature indicators have two time-temperature sensitive components that irreversibly change color at specific ambient temperatures, namely +10°C and +34°C. The +10°C indicator undergoes a complete color change within 14 days at a constant temperature of +12°C.
The indicator strip is divided into three equal windows (A, B and C), allowing users to easily identify the stage of the vaccination process. As for the +34°C indicator, it changes color completely within 3 hours at a constant temperature of 37°C.
This indicator is placed behind window D, allowing users to clearly observe the coloring once the temperature has detected the 34°C limit. These time/temperature functions provide a reliable means for monitoring and identifying potential temperature excursions during vaccine storage and transport, allowing users to understand vaccine quality and efficacy in a timely manner.
