Ultra-Low Temperature Freezer MDF-DU700ZHL-PC 725 L (CAT#: STEM-BC-2681-ZJF)

The MDF-DU700ZHL-PC is an ultra-low temperature freezer designed for research sample preservation. It provides 725 L of storage capacity and operates from -40°C to -86°C. FrostLess technology uses an upgraded inner door, gasket, door frame, and handle structure to reduce frost formation inside the storage environment. The improved insulation structure helps reduce defrosting frequency during routine use. Natural hydrocarbon refrigerant combined with inverter technology supports efficient cooling performance. The refrigeration system helps restore temperature after door opening. A new inverter compressor operates under PID control to help maintain stable internal temperature. The freezer is suitable for laboratories requiring large-capacity ultra-low temperature storage with stable performance.
