Research Sample
Protection
The problem
Your research samples are priceless, mission-critical assets that can be lost if not adequately protected 24/7/365 in ultra-low temperature (ULT) storage. And yet, conventional ULT freezers may be the weakest link in your sample preservation process, especially considering that compressors in nearly all ULT systems are expected to fail at some point during the life of the unit. Freezer failure can be devastating, as compromised temperatures can destroy years of work and threaten future experiments.
ULT Freezer problems are disruptive, place valuable biological samples at risk and can even hinder years of research
Ultra-low freezer failures can also hit without warning. This not only jeopardizes research sample integrity, but also requires that your team take time-intensive and disruptive measures to assure the availability of safe, backup storage. Because compressor-based ULT freezers need regular, ongoing preventive maintenance and must operate within a narrow set of ambient conditions, a lapse in meeting these requirements can also place your precious research specimens at greater risk.
Even a ULT freezer that appears operational can risk sample integrity if temperatures warm excessively during the compressors cycle off periods, slow recovery after door openings or if there are undetected warm positions within the cabinet.
Breakthrough technology that is better at protecting the safety and integrity of your research samples
The Solution
Stirling Ultracold has developed a better, safer technology for preserving your life’s work by replacing compressor-based ULT cooling with the free-piston Stirling engine. This advanced technology addresses the failure modes of compressors in ULT systems.

Up to 16 moving parts to fail
Oil lubrication management
Compressor valves
Stop-start operation
On-off operation – surge currents
Stirling Engine Solution
Don’t wear out – gas bearings
Very few moving parts
No oil
No valves
Continuous operation with 100% adaptive control
No surge currents
Class-defining solutions for biological and pharmaceutical storage.
