Every door opening introduces temperature change, but Stirling ULT freezers are engineered for strong temperature recovery performance to help maintain sample integrity throughout the workday.
Long-term storage capability is only part of the story. The VAULT100 surpasses regulatory thresholds with a thermodynamically engineered cabinet design that sustains temperature uniformity of +/-3°C at -80°C. With better steady-state temperature stability and uniformity at -100°C than most ULT freezers at -80°C, your samples are safer than ever.

Even with regular upkeep, every ULT freezer benefits from a complete annual defrost and deep cleaning.

Over time, frost buildup, dust, spills, and debris can accumulate inside the cabinet and around critical components. Performing a scheduled full defrost allows you to thoroughly inspect and clean the unit while helping maintain peak performance.

This helps:
• Remove excess ice buildup
• Improve airflow and temperature stability
• Maintain door sealing performance
• Reduce strain on the system
• Support long-term reliability and efficiency

During the process, it’s also a great opportunity to:
✔ Inspect gaskets and seals
✔ Check for damage or wear
✔ Clean shelving and racks
✔ Review stored inventory

Preventive maintenance today helps avoid performance issues tomorrow. Routine maintenance = Reliable protection

Less equals More at Stirling Ultracold.

Why? The Stirling VAULT100 takes up less space on your lab floor but allows as much, or more, internal sample storage capacity than competitive models that require more floor space.

Our Stirling engine is not only smaller and operationally efficient, but it is uniquely placed at the top of your freezer, taking up much less space and leaving more capacity to store more samples that will remain safe in the industry’s smallest footprint.
