Designed for use in research, clinical, and industrial laboratories, this high-capacity freezer features a direct cooling system with a full cold wall design that ensures uniform temperature distribution throughout the chamber. Evaporator pipes embedded in the back, sides, top, and bottom walls remove heat evenly, while their closer spacing near the top promotes natural air convection for superior uniformity. This configuration eliminates temperature gradients and prevents the formation of hot or cold spots commonly found in conventional freezers.\n\t\u003cbr\u003e\u003cbr\u003e\n\tBuilt with durability and security in mind, the Sanyo MDF-U731M features a sturdy steel cabinet with superior insulation for energy-efficient operation and dependable thermal performance. The manual defrost system maintains constant chamber temperatures without introducing temporary fluctuations, making it well-suited for applications requiring strict stability, such as GMP-compliant processes or the preservation of highly temperature-sensitive materials. A front-mounted microprocessor control panel provides easy access to real-time monitoring, memory backup, and user calibration functions, while integrated safety features include high\/low temperature alarms, power failure alerts, a breaker switch, and a remote alarm contact. The freezer’s lockable door, balance hinge, and adjustable wire shelving add convenience and security, while built-in casters and leveling feet ensure mobility and stability. With its advanced temperature control, reliable performance, and flexible storage configuration, the Sanyo MDF-U731M offers an efficient, long-lasting solution for laboratories that demand precision and sample integrity.\u003cbr\u003e\u003cbr\u003eAll of our equipment is fully tested to perform at factory specifications before being shipped.\n\t\u003cbr\u003e\u003cbr\u003e\n\t\u003cdiv class=\"included-box\"\u003e\n\t\t\u003cspan class=\"included-header\"\u003eINCLUDED:\u003c\/span\u003e\u003cbr\u003eThe Sanyo MDF-U731M -30C Upright Biomedical Freezer includes:\n\t\t\u003cul\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eKey\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e4 x Shelves\n\t\t\t\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eNIST Calibration and Preventative Maintenance Report\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003ePower Cord\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eOperator's Manual\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eFull 180 Day Parts and Labor Warranty\u003c\/li\u003e\n\t\t\u003c\/ul\u003e\n\t\u003c\/div\u003e\n\t\u003cbr\u003e\n\t\u003ch2\u003eSanyo MDF-U731M -30C Upright Biomedical Freezer Specifications\u003c\/h2\u003e\n\t\u003ctable\u003e\n\t\u003ctbody\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tTemperature Range\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t-20°C to -30°C\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tVolume\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t24.3 cu. ft.
