Ultra-Low Temperature Freezers

Ultra-low temperature freezers reaching -80°C to -86°C for long-term preservation of biologics, vaccines, enzymes, and research specimens.

Ultra-low temperature (ULT) freezers are critical for the long-term preservation of biologics, vaccines, enzymes, DNA, and research specimens that must be stored at -80°C or below. VitaFreeze offers ULT freezers from So-Low Environmental Equipment, designed for reliable, energy-efficient operation at -40°C to -86°C. These freezers are used by biobanks, pharmaceutical companies, university research labs, fertility clinics, and public health repositories where sample loss is not an option. When selecting an ultra-low freezer, the most important factors are temperature stability, holdover time during a power outage, energy efficiency, and compressor reliability. Our catalog includes upright and chest ULT units with capacities from compact to 30+ cubic feet, many with quick-ship availability. All units include a manufacturer warranty and are backed by VitaFreeze's direct support. Filter below by temperature range, capacity, and configuration to find the right ultra-low freezer for your storage requirements.
