In medical technology, pharmaceutical logistics and hospital management, reliable temperature monitoring of blood bags is essential to ensure the safety and usability of blood products.
Even minor deviations from the required storage temperature can compromise the quality of blood components.
With the Hemo Temp II indicator, KAGER provides a simple and reliable solution for thermal validation of blood bags during transport and storage.
Reliable temperature indicator for blood transport
The self-adhesive Hemo Temp II measuring strip, part of the KAGER Medical Line (KML), allows quick visual monitoring of the core temperature of blood bags.
The four-level temperature scale clearly indicates whether the temperature remains within the safe range:
- 1–3 °C
- 4–6 °C
- 7–9 °C
This makes it easy to verify whether the critical temperature threshold of 10 °C has been exceeded during storage or transport.
The indicator is applied directly to the blood bag before shipment and monitors the temperature during the entire logistics process.
Clover symbol signals temperature threshold breach
To activate the indicator, KAGER provides a compact incubator device capable of heating up to twelve labels simultaneously to 42 °C within 60 seconds.
This process activates a thermochromic liquid crystal inside the indicator and reveals a blue clover symbol on the display scale.
This symbol confirms that the indicator is ready for use.
A key feature:
- The temperature display is reversible
- The clover symbol is irreversible
If the clover remains blue, the temperature limit has not been exceeded.
If the symbol turns grey or disappears, the blood bag temperature has exceeded 10 °C, meaning the blood product must be discarded for safety reasons.
Supporting quality assurance in blood logistics
The Hemo Temp II temperature indicator helps organizations involved in:
- blood donation services
- blood processing centers
- hospitals
- pharmaceutical logistics
to maintain blood product quality assurance and ensure cold chain validation.
When unused blood bags are returned, the indicator provides immediate verification that the cold chain has remained intact.
