Low Temperature Freezer MDF-MU539HL-PC 504 L (CAT#: STEM-BC-2707-ZJF)

The MDF-MU539HL-PC is a low temperature freezer designed for research sample preservation. It provides 504 L of storage capacity and operates from -20°C to -30°C. Natural hydrocarbon refrigerant combined with inverter technology supports efficient cooling performance. The system helps restore internal temperature after door opening. A double-door design reduces cold air loss when samples must be removed during a temperature alarm. This design helps limit temperature changes affecting stored samples. Adjustable shelves allow flexible storage according to sample dimensions. Self-diagnostic functions, high and low temperature alarms, and error code display support safer sample storage.
