-150°C Cryogenic Freezers SANYO MDF series cryogenic freezers maintain uniform temperature of -150°C for stable, long-term preservation of cells and tissue. SANYO V.I.P.™ PLUS Cryogenic Series -150°C ultra-low temperature freezers achieve more storage capacity than a conventionally insulated freezer without increasing footprint. -150ºC Cryogenic Freezers Model Number MDF-C2156VANC Volume (cu.ft.) 8.2 231 L Exterior Dimensions (w x f-b x h) 68.1" x 30.1" x 39.8" 1730 x 765 x 1010 mm Storage (2"/ 51 mm boxes) 150 The newly developed refrigeration system and freezer structure offers a quiet environment. Storage (3"/76 mm boxes) 105 Storage (2ml vials in boxes) 15,000 Voltage, Power Connection 208/230V NEMA 6-15 Uniform Cryogenic Temperatures Mechanically refrigerated design promotes better top-to-bottom uniformity than liquid nitrogen vapor-phase storage. V.I.P.™ PLUS Design Patented revolutionary vacuum insulation cabinet construction reduces wall thickness and achieves more storage capacity than a conventionally insulated freezer without increasing the footprint. SANYO-Designed Refrigeration Designed by SANYO specifically for rugged cryogenic temperature applications in a laboratory environment; CFC-free refrigerants only. Microprocessor Temperature Control with Digital Design Precise setting and temperature control. The temperature inside the freezer can be set and monitored easily by means of precise microprocessor temperature control with an LCD graphic display. Adjustable high/low temperature alarm; power failure alarm; filter check alarm; door ajar alarm; part replacement time notification. LCD Control Panel LCD microprocessor controller features a full-alarm package with a status alert monitoring system. The monitoring system records internal temperature up to one month and history of door openings and closings. Comparison of temperature distribution in a liquid nitrogen freezer (vapor phase) and SANYO's MDF-C2156VANC mechanically refrigerated cryogenic freezer. Graph shows temperatures at different locations within the chamber. This data demonstrates that 100% of the MDF-C2156VANC storage space maintains uniform storage temperatures safely below -130ºC, while temperature in LN2 vapor system is dependent on storage location. Ideal Alternative to LN2 Storage Mechanical Preservation Freezer preservation provides users with numerous advantages; uniform cryogenic storage temperatures, no worries about sample contamination, no liquid supply problems, no danger of sudden liquid eruptions and low operational costs. Built-In LN2 Backup System Automatically injects LN2 to maintain temperature during prolonged power outage, (LN2 tank not included). Mechanical Refrigeration Lowers LN2 consumption and mitigates safety concerns, reduces cost of ownership, minimizes chance of cross-contamination among stored samples due to vial breakage at extreme temperatures.
