Description
True Portable ULT Storage for Remote Clinical Care & Cold Chain Transport
The Stirling Ultracold ULT25NEU portable ultra-low temperature freezer is the only truly portable ULT freezer available today, purpose-built to support cold chain sample preservation, biologic transport, and remote clinical trials anywhere in the world.
Designed to overcome the limitations of dry ice and bulky compressor-based systems, the ULT25NEU delivers precisely controlled ultra-low temperature storage from -86°C to -20°C in a compact, lightweight form factor. It enables healthcare providers and research teams to safely preserve, transport, and store temperature-sensitive biological materials directly at the point of patient care, even in remote or decentralized locations.
Powered by free-piston Stirling engine technology, this portable ULT freezer offers the same performance, reliability, and sample protection as larger undercounter and upright ULT freezer models—without compromising mobility or efficiency.
Key Benefits of the ULT25NEU Portable ULT Freezer
True Portability for Field & Clinical Use
Weighing only 46 lbs. (21 kg), the ULT25NEU is lightweight, compact, and easy to ship globally. Its portable design makes it ideal for remote clinical trials, mobile healthcare units, and decentralized research programs.
Safeguard Cold Chain Integrity at the Point of Care
Unlike dry ice, which presents handling challenges and temperature instability, the ULT25NEU provides consistent, precisely controlled ultra-low temperatures, protecting the viability of high-value biologics and clinical samples during transport and storage.
Plug-and-Play Power Anywhere
The ULT25NEU plugs into any standard 110V–240V outlet worldwide and can also operate on 12V DC power using an automotive adapter, enabling flexible deployment in clinics, vehicles, and temporary field locations.
Widest Temperature Range in a Portable ULT
Safely store samples across a broad range of -20°C to -86°C, supporting a wide variety of biologics, regenerative therapies, and temperature-sensitive specimens.
Compact Footprint with Surprising Storage Capacity
Despite its small size, the ULT25NEU holds 18 standard 2-inch boxes within a 25-liter (0.9 cu. ft.) interior, maximizing usable capacity without sacrificing portability.
Remote Monitoring & Compliance Support
Optional SenseAnywhere™ wireless monitoring enables real-time temperature tracking, alerts, and secure cloud-based data storage—supporting regulatory compliance and 24/7 oversight from anywhere.
Ultra-Low Energy Consumption
Engineered for efficiency, the ULT25NEU consumes less than 2.8 kWh/day at -80°C, making it one of the most energy-efficient portable ULT freezers available.
Environmentally Sustainable Cooling
Using 100% natural refrigerants, this portable ULT freezer eliminates the need for special export shipping classifications and supports environmentally responsible cold storage practices.
