MDF-1156/1156ATN

Ideal for long term preservation of biologicals, blood components and various 

cell line, SANYO preservation systems employ microprocessor control to 

maintain a high-precision temperature environment. They are not affected by 

ambient temperature, minimizing uneven temperature distribution within the 

chamber, and a temperature rise during door opening.
