Portable ULT Freezer
Uniquely Portable and Reliable Ultra-Low Temperature Storage
Small, Lightweight, Portable Storage
The ULT25NEU is the only truly portable ultra low temperature (ULT) freezer available today for bringing cold chain samples and biological products to patients at clinic remote sites. It provides safe and reliable ULT freezer storage in the field and on the go, so you can:
- Safely preserve and deliver biologics at the clinical point of patient care, anywhere in the world
- Collect temperature-sensitive samples and specimens at remote clinical trials
- Easily deploy long-term storage of viable biological materials, anywhere there is a power outlet with our portable ULT freezers.
Temperature control and handling limitations of dry ice storage can risk the viability of your valuable samples in the field, while compressor-based freezers are too unwieldy and unreliable for deployment at remote sites. The revolutionary ULT25NEU ultra-low temperature freezer was designed to solve these problems. With its compact and field-proven, free-piston Stirling engine technology, it brings portable, precisely controlled ULT freezer storage anywhere there is a need for patient care, testing or specimen collection.
But this portability and small footprint does not come with compromise. The ULT25NEU freezer is a 25-liter (0.9 cu. ft.) capacity ULT freezer with the same performance and reliability of our larger undercounter and upright ultra-low temperature freezer models.
Built for clinical and health care markets
