An Ideal Freezing Environment with VIP Plus Design
In Ultra-Low temperature freezers, effective insulation is extremely critical since the temperature difference between the outside and the inner compartment can be as high as 115 deg C.
-150 deg 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 damaging amorphous ice crystals from recrystallizing within and outside the cells. When ice crystals become amorphous, they are stored using cryoprotective agents such as glycerin 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 deg C is the recrystallization point of pure water in the ultra-low temperature zone. For a mixed solution containing Me2SO and other cryoprotectants, recent research confirms that recrystallization occurs around -115 deg C. Samples maintained in an ultra-low temperature freezer at -150 deg C, far lower than the recrystallization point, can be semipermanently preserved. Such preservation maintains vitrification without further crystallization within and outside cells. Recent findings show that preserving cattle sperm at -135 deg C is insufficient, and require temperatures of at least -148 deg C. These cases show the increased necessity of -150 deg C freezing in an array of cryogenic applications.
