MDF-C2156VANC: 8.2 cu. ft. VIP™ Plus -150°C Cryogenic Freezers

Scientists set a low temperature record without harmful CFCs. Now, the mechanically refrigerated cryogenic freezers achieves stable long-term preservation of cells and tissues. Ideally suited for ultra low and cryogenic storage in laboratories, long-term preservation and storage of blood, specimens and components, and in testing of various types. New V.I.P. PLUS™ technology maximizes storage capacity over conventionally insulated models. These preservation systems employ advanced technology to insure a high precision temperature environment.   
  
-150°C Cryogenic Temperature Freezer Ensures Stable Cell and Tissue preservation  
  
Cryopreservation allows for storage of biological materials at ultra low temperatures, while minimizing the level of freezing damage to cells. An important factor to consider when preserving cells or tissue at cryogenic temperatures is to prevent amorphous ice crystals from recrystallizing within and outside the cells. These ice crystals increase the degree of freezing damage to cells. When ice crystals become amorphous, they are stored using cryoprotective agents such as glycerine and dimethyl sulfoxide (Me2SO). The speed of ice crystal formation is thus further restricted during preservation below a certain temperature, and complete vitrification is possible. -130°C is the recrystallization point of pure water in the ultra-low temperature zone. This is the temperature at which amorphous ice crystals recrystallize. For a mixed solution containing Me2SO and other cryoprotectants, recent research confirms that recrystallization occurs around -115°C. Thus samples maintained in an ultra-low temperature freezer at -150°C, far lower than the recrystallization point, can be semipermanently preserved. Such preservation maintains vitrification without further crystallization within and outside cells. Other recent findings show that preserving cattle sperm at -135°C is insufficient, and also that superconductivity experiments require temperatures of at least -148°C. These cases show the increased necessity of -150°C freezing in a diverse array of cryogenic applications.
