Description
The Across International Ai RapidChill G34he -86°C Ultra-Low Temperature Freezer is designed for high-capacity ultra-low temperature storage of sensitive biological samples and vaccines. With an expansive 34 cubic foot storage chamber, this Energy Star certified ULT laboratory freezer provides dependable performance for research laboratories, pharmaceutical facilities, hospitals, and biotech institutions.
The RapidChill G34he features advanced Vacuum Insulated Panel (VIP) technology and an energy-efficient hydrocarbon refrigeration system, enabling fast pull-down times, excellent temperature uniformity, and extremely low power consumption. The system can reach -86°C in approximately 6 hours while maintaining temperature stability within ±3°C.
Unlike most ULT freezers, the G34he is fully compatible with both 50Hz and 60Hz power, allowing it to operate in North America, Europe, Asia, and South America, making it ideal for global laboratories and research facilities.
Equipped with dual compressors, long-term USB data logging, RS-485 monitoring, and advanced alarm protection, the RapidChill G34he delivers secure and reliable storage for critical laboratory materials.
