Ultralow Freezers FAQ
What is an ultralow temperature (ULT) freezer, and why is it essential?
An ultralow temperature (ULT) freezer is a critical piece of laboratory equipment designed to preserve sensitive biological materials such as cancer cells, stem cells, tissue samples, and other temperature-sensitive specimens. Operating at temperatures as low as -86°C, ultralow freezers provide the stable environment necessary for long-term storage and research continuity.
Why Ultralow Freezers Are Essential:
- Preservation of Sample Integrity: Maintaining extremely low temperature stability ensures that biological samples remain viable, preventing molecular degradation.
- Critical for Research: Many fields, including genomics, regenerative medicine, and pharmaceutical research, rely on ultra low freezers to store high-value and irreplaceable materials.
- Prevention of Costly Losses: Failure to store samples properly can lead to the loss of years of research and significant financial investments.
What temperature range do NuAire ULT freezers offer?
NuAire's ultralow temperature (ULT) freezers are engineered to provide reliable and precise cooling within a temperature range of -86°C to -40°C, with a commonly used set point of -80°C.
