Product Description

The dual cooling system offers the highest level of sample protection through the use of two independent refrigeration systems that maintain -86°C temperature. The two circuits in this ultra low temperature lab freezer work together for fast temperature recovery, while the secondary system keeps the temperature at -70°C if a service event occurs. With two independent systems, each sustaining ultra-low temperatures, your samples remain safe. Optional CO2 backup provides and extra layer of protection.

Performance & Reliability
Robust refrigeration system with purpose built compressors that are made for the application. Unique internal heat exchange increases performance envelope, tolerates high ambient temperatures
Security Control & Monitoring
Eye level door mounted color LCD touchscreen. All setpoints, alarms, data download preferences and notifications are accessed through a password-protected interface. Data management center with USB port.
Space Saving VIP panels
VIP Plus insulation ensures exceptional insulation value with a compact footprint. performance envelope, tolerates high ambient temperatures
Advanced Frost Control & EZ latch
The Advanced Frost Control System and EZlatch door handle represent the key to an integrated access and frost mitigation system. This feature minimizes frost, protects stored samples, extends freezer life and makes ergonomic, one-handed door openings easy.
