Ultra-Low Temperature Freezer -86°C, 408-838L, Touchscreen
Ultra-low temperature freezer providing -86°C storage with microprocessor control, multiple capacity options, and comprehensive temperature monitoring for critical biological sample preservation.
The -86°C Freezer provides ultra-low temperature storage for critical biological samples requiring preservation at temperatures down to -86°C. This microprocessor-controlled freezer features a 7-inch LCD touch screen interface and offers multiple capacity options (408L, 588L, 838L) to accommodate varying laboratory storage requirements. The system maintains temperature uniformity within ±4°C throughout the storage compartment and provides temperature stability within ±6°C.
Recovery performance is optimized for laboratory workflows, with recovery times to -75°C ranging from 16-35 minutes depending on capacity. The comprehensive alarm system includes audible and visual alerts for high and low temperatures, sensor faults, and condenser blockage conditions. Temperature accuracy of ±0.1°C ensures precise environmental control for temperature-sensitive specimens and reagents.
How It Works
The -86°C freezer operates using a cascade refrigeration system that achieves ultra-low temperatures through sequential cooling stages. The microprocessor control system continuously monitors internal temperature using precision sensors and adjusts compressor operation to maintain the setpoint within ±0.1°C accuracy. The refrigeration cycle removes heat from the storage compartment through multiple heat exchangers, allowing the system to reach and maintain temperatures as low as -86°C.
Temperature uniformity is maintained through strategic air circulation patterns that distribute cold air evenly throughout the storage volume. The 7-inch LCD touch screen provides real-time temperature display and system status monitoring, while integrated alarm systems detect deviations from normal operating parameters. The control system automatically initiates corrective actions when temperature excursions are detected, ensuring sample integrity during storage.
