A temperature indicator used to keep track of blood bag temperature during storage and transit, the Blood Temp 10 is designed with a yellow activation window along with a white breach window. When the Blood Temp 10 is activated, a green line appears on the yellow activation window while the breach window remains white. When the temperature breaches and exceeds 10°C, the Blood Temp 10 sends out visual alerts to its handlers. The Blood Temp 10 is not only shelf-stable and can be stored at room temperature, but it is also compliant with all FDA and AABB requirements.
