Ultra-Low Temperature Freezer MDF-DU703VXHL-PC 729 L (CAT#: STEM-BC-2685-ZJF)

The MDF-DU703VXHL-PC is an ultra-low temperature freezer designed for secure research sample preservation. It provides 729 L of storage capacity and operates from -40°C to -86°C. The TwinGuard ECO dual refrigeration system uses two independent refrigeration circuits to achieve ultra-low temperature storage. If one circuit is affected, the remaining circuit can maintain -75°C to reduce the risk of sample damage. Natural hydrocarbon refrigerant combined with inverter technology supports efficient cooling. The cooling system helps restore temperature after door opening. A new inverter compressor operates under PID control to maintain stable internal temperature. Low-speed compressor operation supports lower energy use during stable storage conditions.
