Because of the COVID-19 pandemic, vaccine shipping at extremely low temperatures has been in the news lately. But, such cold temperature shipping is really not new. Shipping and storing with dry ice and liquid nitrogen are the norm for some industries and products.
Dry ice has a temperature of -109.3°F (-78.5°C) and is used for shipping products such as biologics, certain frozen foods, medical supplies, and of course vaccines such as the Pfizer COVID-19 vaccine. Dry ice shipments are also used for sensitive carbon fiber prepreg (composite materials such as carbon, graphite, or glass fibers that are “pre-impregnated” with resins and then cured) and other TATS materials.
Cryogenic shipping involves shipping at temperatures below -238°F (-150°C). Such extreme temperature shipping requires liquid nitrogen rather than dry ice and is typically used for biologic materials for laboratories, hospitals, tissue banks, and fertilization clinics.
In shipping and storing such temperature-sensitive materials, it is more important than ever to ensure that the required extreme temperatures are being maintained and to be able to take quick action if they are not. Data loggers that are purpose-built for such extreme conditions are required.
DeltaTrak offers a series of loggers to monitor the temperatures for materials shipped and stored in both dry ice and liquid nitrogen. This range of data loggers includes models that are reusable or single-use with features such as real-time reporting, 24/7 cloud service, and PDF backup.
The following data loggers monitor ultra low temperatures during storage or transport using either dry ice or liquid nitrogen:
- FlashLink® RTL Prime 3G Cryo In-Transit Logger, Model 22368
- FlashLink® -200°C Reusable Data Logger with Cryo Probe, Models 40565, 40565-01
- FlashLink® RTL 3G Cryo Reusable Data Logger, Models 22370, 22370-01
DeltaTrak also offers loggers purpose-built for dry ice shipments:
- FlashLink® Dry Ice USB PDF In-Transit Logger, Model 40701
- FlashCheck® Certified Min/Max ULT Thermometer, Models 12239, 12239-02
- FlashLink® Certified Vaccine ULT PDF Data Logger, Models 40570, 40570-01
