Why choose Cryoguard indicators?

Cryoguard Thermal Exposure Indicators are:

Unique. No other temperature sensor provides an at-a-glance warning of thermal exposure from -40°C down to -150°C.

Simple. A green indicator tells you that the monitored material did not suffer potentially damaging thermal exposure.

Economical. Eliminate downloading and returning data loggers, and interpreting data logger print outs.

Versatile. Cryoguard indicators fit in partitioned freezer boxes, attach to most cryovials or snap onto standard cryovial freezer canes.
