The Harris® Cryostar® cryogenic storage freezer offers an alternative to liquid nitrogen vapor for the long-term storage of biological materials at cryogenic temperatures. Operating at temperatures of -140° C and -150° C, chest models employ a single-compressor refrigerator system. Uniform temperatures below the critical -130°C glass transition temperature of water are maintained at all shelf levels to improve cell viability.
    All Cryostar functions are monitored with a standard microprocessor controller for preemptive monitoring of intermittent or chronic conditions affecting system performance, even when the freezer is unattended. The controller features intuitive data entry and display for easy operation. Standard features on low-profile Cryostar cabinets include a minimum of five inches of CFC-free urethane insulation, insulated sub-lids, a keyed lidlock and a one-inch diameter access port.
