Cryoguard LLC

Cryoguard LLC provides indicators that monitor thermal exposure at 10 preset signal temperatures, from -5 °C down to -150 °C.

Indicators irreversibly change color from green to red within 0.5-2 hours at their signal temperature and within minutes at 10 °C above their signal temperature. At 25 °C below their signal temperature, indicators remain green. Therefore, users can tell in an instant that thermal exposure never compromised the monitored material.

Cryoguard indicators are widely used to assure the quality of cryopreserved eggs, sperm, cord blood, embryos, bone marrow, stem cells, bone grafts, blood plasma, vaccines, biologics and premixed epoxy adhesives during shipping, storage and handling. Because the indicators provide an at-a-glance warning of thermal exposure via color change, they can provide a hassle-free alternative to data loggers and verify compliance with FDA, CDC and CAP guidelines for shipping/storing heat-sensitive medications and specimens.
