For the past 30 years, Cryoguard Corporation has been meeting your needs for ultra low temperature control.

Our Cryoguard Thermal Exposure Indicators do exactly what the name implies: They signal thermal exposure. The indicators irreversibly change color from green to red when exposed to temperatures above pre-set signal temperatures. That means you get a reliable report of thermal exposure, even at temperatures as low as -120 degrees Celsius!

With Cryoguard indicators, you can achieve quality assurance when shipping or storing frozen materials in liquid nitrogen, nitrogen vapor or dry ice. You'll never have to wonder whether your products got too warm during transit - and potentially became compromised as a result. Put Cryoguard indicators in freezer storage boxes to monitor thermal exposure during their routine removal from freezers.

Cryoguard indicators are used to monitor: cord blood, bone grafts, tissue samples, vaccines, sperm, embryos, eggs, adhesives and many other materials stored at or below -70 degrees Celsius.

Do you want to feel more confident when handling cryogenic materials? Try the product today!  Join the other leading hospitals, fertility clinics, stem cell labs, universities and aerospace companies who rely on Cryoguard indicators to ensure proper handling of heat-sensitive materials.
