Features

The Cryogenic MDF-1156 Ultra Low Temperature Freezer is a mechanically refrigerated cryogenic freezer without harmful CFCs. This Ultra Low Temperature Freezer achieves stable long-term preservation of cells and tissues.

New VIP PLUS technology maximizes storage capacity over conventionally insulated models. The Cryogenic MDF-1156 Ultra Low Temperature conservation system employs advanced technology to insure a high precision temperature environment.

Specially designed compressor and cascade refrigeration system for an ultra-low temperature of -152ºC

Highly efficient compressors have been specially developed and incorporated in the freezing unit. With a powerful low noise design afforded by traditional ultra-low temperature technology, this freezer delivers durable, stable cooling.
