Cryoguard^TM Thermal Exposure Indicators signal thermal exposure or temperature abuse of cryopreserved materials. The indicators are used to monitor perishable materials, such as frozen blood plasma, stem cells, sperm, tissue samples, clinical samples and premixed epoxy adhesives, during transit and storage. Indicators can also be used to detect failures or fluctuations in refrigeration or freezers.

Cryoguard Thermal Exposure Indicators can be used to:

• Validate maintenance of an appropriate environment during transit

• Encourage careful handling of monitored materials. Supplied alert labels affixed to shipping containers indicate a monitored environment within

• Remind personnel to minimize the time materials are kept out of the freezer

• Warn against unsafe use and inappropriate studies of thermally exposed material

Cryoguard Indicators are designed to:

• Fit in 0.5" partitions in freezer inventory/storage boxes
• Attach to nunc brand cryovials
• Snap onto standard cryovial freezer canes
• Be wired to cryopreserved samples
