Description
Next-Generation ULT Storage with an Industry-Leading -100°C to -20°C Range
The Stirling Ultracold VAULT100 ultra-low temperature freezer sets a new benchmark for sample protection, temperature uniformity, sustainability, and intelligence. As the first ULT freezer on the market with a -100°C to -20°C temperature range, the VAULT100 delivers unmatched control and confidence for laboratories handling their most valuable biological materials.
Engineered with a new, more robust M6D free-piston Stirling engine, the VAULT100 provides best-in-class temperature uniformity and setpoint adherence, advanced onboard diagnostics, and predictive analytics—ensuring your samples are safer, your operations more reliable, and your sustainability goals fully supported.
Why the VAULT100 Is Better in Every Sense
Unmatched Temperature Performance
The VAULT100 delivers industry-leading steady-state temperature control, achieving:
-
±3°C uniformity (9-position) at -80°C
-
±0.2°C stability (single-position) at -80°C*
With better stability at -100°C than many ULT freezers achieve at -80°C, the VAULT100 exceeds regulatory expectations and provides unparalleled sample protection.
*Within testing protocol margin of error
First ULT Freezer with a -100°C to -20°C Range
This expanded temperature range allows laboratories to:
-
Store ultra-sensitive biologics at colder-than-standard ULT conditions
-
Improve long-term viability of high-value samples
-
Maintain flexibility for evolving protocols and future research needs
Fast Temperature Recovery for Real-World Lab Use
Frequent door openings are unavoidable in busy labs—and slow recovery can threaten sample integrity.
The VAULT100 is engineered for rapid recovery, even with large temperature differentials between ambient conditions and cabinet setpoints. When operating down to -100°C, samples may never be exposed to temperatures above -70°C during or after a typical door opening, helping safeguard critical research.
Advanced M6D Free-Piston Stirling Engine Technology
At the heart of the VAULT100 is the new M6D Stirling engine, designed for maximum reliability and efficiency:
-
Few moving parts in contactless linear motion
-
Gas bearings eliminate the need for oil
-
No compressors, reducing mechanical failure points
-
Continuous modulation (not stop/start cycling) for smoother operation and longer life
This advanced design significantly lowers failure risk while delivering consistent, ultra-precise temperature control.
360-Degree Sustainability Without Compromise
The VAULT100 reflects Stirling Ultracold’s holistic sustainability approach, combining performance, efficiency, and environmental responsibility:
-
ENERGY STAR® certified
-
ACT® Label from My Green Lab confirming low Environmental Impact Factor (EIF)
-
Uses only 5.8 kWh/day at -80°C steady state**
-
Larger storage volume per square foot reduces facility footprint, plug load, and carbon impact
*ENERGY STAR Final Test method at -80°C setpoint
