MDF-U730M biomedical storage freezer is offered for long-term preservation and storage of specimens and components, biologics, reagents, and test samples of various types. It incorporates the features required for laboratory grade freezing of enzymes and vaccines, including temperature uniformity, microprocessor control, and large, flexible capacity. Two access ports, casters, remote alarm contacts, and security features (a keyed door lock and padlock handle) are standard. Evaporators are located in the walls not only along both sides and the back of the chamber, but also on the top and the bottom of the chamber to ensure maximum cooling performance. No condenser fan is required with this design. In combination with low dB level compressor, this unit is quiet and thus suitable for in-lab installations.
