Designed with a space-saving compact footprint that slides effortlessly under standard lab bench spaces, this 120V freestanding unit features an internal capacity of 5.0 to 5.6 cubic feet (142 to 159 liters). Powered by a highly efficient, base-mounted 360W compressor utilizing eco-friendly, CFC-free R-134a refrigerant, the freezer maintains an adjustable operational thermal horizon from -15 C down to -20 C (adjustable down to -24 C via an internal hydraulic thermostat dial). Equipped with thick, foamed-in-place polyurethane insulation, a solid left-hinged door with magnetic gasketing, three fixed wire interior shelves, and three convenient built-in door shelves, this manual-defrost unit prevents sample dehydration or erratic temperature spikes caused by auto-defrost heat cycles.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Enclosure Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eStable Manual Defrost Architecture:\u003c\/b\u003e Engineered strictly with a manual defrost system that eliminates periodic, automated heating cycles common to residential units.
