Gram-Bioline Laboratory Fridges and 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 Top-to-bottom temperature uniformity dramatically improved Lowering operating costs then Liquid Nitrogen freezers of similar capacity 100%of storage volume 156 liter is usable washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal FEATURES CFC-free refrigerant. Stable cryogenic temperature of -148 C~-156 C. without Liquid Nitrogen Patentes, Cryo refrigeration system are mix refrigerant flow systems.
