Eppendorf CO₂ and LN₂ Freezer Back-up Systems

Freezer Back-up Systems: Eppendorf CO₂ and LN₂ Freezer Back-up Systems – Emergency Protection for ULT Storage

Reliable Freezer Back-up Systems for Critical ULT Sample Protection

The Freezer Back-up Systems: Eppendorf CO₂ and LN₂ units provide essential emergency protection for ultra-low temperature (ULT) freezers in laboratories, biobanks, and research facilities. Designed for New Brunswick Scientific ULT freezers, these systems activate automatically during power failure or compressor malfunction to maintain safe internal temperatures using liquid CO₂ or liquid nitrogen (LN₂).

The Eppendorf Freezer Back-up Systems feature a freestanding control module, sensor probe, solenoid valve, and transfer lines, ensuring precise operation and secure sample protection. Battery-backed control allows continued performance during outages, providing confidence that critical biological materials, reagents, and pharmaceuticals remain stable even in emergencies.

These freezer back-up systems can be factory-installed or retrofitted to existing ULT freezers, making them a flexible and dependable solution for any cold-chain safety plan.
