Follett Scientific PHCbi FZRC8-220 8.2 cu. ft. -150°C Cryogenic Chest Freezer

The Follett Scientific PHCbi FZRC8-220 cryogenic chest freezer offers an advanced solution for the long-term storage of critical laboratory samples. This 8.2 cubic foot unit safely preserves biological materials in an air phase environment at -150 degrees Celsius, removing the standard reliance on liquid nitrogen as a primary cooling source. By utilizing a robust hybrid auto-cascade refrigeration system, this chest freezer achieves rapid pull-down speeds and outstanding temperature uniformity without stratification. It provides a highly reliable and secure environment for scientific and research facilities needing strict temperature control without the frequent maintenance and hazardous conditions of traditional LN2 storage.

Designed for high capacity within a compact footprint, the freezer features patented VIP Plus cabinet insulation technology to maximize internal volume while minimizing wall thickness. Operators can easily monitor and adjust settings using the microprocessor-based controller, which pairs a clear LCD graphic display with a highly accurate platinum RTD sensor. For added sample security, the unit includes an insulated locking lid with sub-lids to retain cold air and a standard LN2 back-up system requiring an external supply. Comprehensive visual and audible alarms warn users against power failures, open lids, or temperature deviations, ensuring absolute peace of mind.
