Cole-Parmer presents the StableTemp 20.4 cubic foot upright ultra low freezer. Designed to meet cold storage needs to -86°C, the cabinet has insulation panels to improve temperature stability, and separate inner storage chambers with insulated doors providing independent access to storage space, minimizing frost buildup, and ensuring protection of stored samples. A microprocessor controller with a push-button control displays an easy to read operation status display. Large LEDs show a quick view of operation parameters. Audible and visual alarms notify high and low temperatures, power failures, sensor errors, and alerts such as clean filter, door ajar, hot condenser, and high ambient temperature.
