Cryo-Freezers

Operon Cryogenic Temperature Without Liquid Nitrogen

Stable, long-term preservation of cells and tissues can be achieved by reaching ultra-low temperatures. Temperatures, generally lower than -130 degree C, create a state where ice crystals become amorphous. That is the recrystallization point of pure water of the glass transition (vitrification) temperature of water.

Even if cryo-protective agents are used to assist in the preservative function, recrystallzation can occur at opproximately -115 degree C. Recrystallzation within and outside the cells may cause damage to the samples, Maintaining an ultra-low temperature of -156 degree C, far lower than the recrystallzation point, maintains vitrification of the samples without crystallization.


GENERAL SPECIFICTIONS

-100 C to-156 C.
Fast cooling
Downfeed evaporator for most efficient refrigerant flow
High capacity air-cooled condenser with dual condenser fans, aerodynamically designed fan blades

CUSTOMER BENEFITS

Safer, more convenient then liquid Nitrogen freezer
Superior in cost/performence to liquid nitrogen freezer

APPLICATION

Cryogenics freezers, Conqueror are designed for long-term storage of biologicals at uniform temperatures of -156 degree C, safely below the -130 degree C. glass transition temperature of water
cell viabiliy is improved becausd biologically relevant, thermally driven reactions are not known to occur
