Safe-T-Vue® 6 Blood Temperature Indicators

AABB Standards Compliant seal for blood temperature indicator Safe-T-VueNonreversible Temperature Indicators for Blood Products, Plasma and RBCs

Safe-T-Vue® 6 is a temperature-sensitive indicator that takes the guesswork out of whether or not blood products, plasma and RBCs can safely be reissued.

Safe-T-Vue 6 on a blood bag

Ideal for blood banks, blood collection centers and transfusion services, Safe-T-Vue 6 is attached directly to blood bags while they are refrigerated or in temporary storage. The indicator changes color from white to red when the blood (or other temperature sensitive product) has reached or exceeded 6°C.

Because it is nonreversible, Safe-T-Vue 6 will indicate that a higher temperature condition existed even if the temperature eventually returns to a lower level. As long as the indicator remains white, temperatures have remained at or below 6°C and the blood product may be reissued.

Temperatures accurate to within +/- 0.4°C.
