Stirling Ultra-Low Freezers
Ultra-low temperature freezers are ideal for storing valuable laboratory materials such as biological samples, vaccines, enzymes, viruses, bacteria, cell preparations, and tissue samples.
Ultra-low freezers come in various sizes and designs. Laboratories can choose from designs such as ULT chest freezer, upright ULT freezer, and ULT bench-top freezer. Your ultra-low temperature freezer size can depend on how much storage is required and the available footprint space in the lab.
Stirling Ultracold offers ultra-low temperature freezers that are innovative -with deliver best-in-class service. With a reputation that you can trust, Stirling Ultracold freezers store samples efficiently with precise control.
Model ULT25NEU
Uniquely Portable and Reliable Ultra-Low Temperature 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 portable Sterling 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-litre (0.9 cu. ft.) capacity ULT freezer with the same performance and reliability of Sterling's larger undercounter and upright ultra-low temperature freezer models.
