Thermo Fisher's cryogenic freezers operate at uniform and stable cryogenic temperatures of -140 and -150C, offering a safe and convenient method for the long-term storage of biological materials.
At such low temperatures, metabolic activity is not known to occur, greatly increasing cell viability.
As such, these freezers fulfil the requirements of many laboratories, including those of clinical research, life sciences and pharmaceutical organisations.
Using advanced mechanical refrigeration technology, the freezers offer advantages over units that rely on liquid nitrogen as a cooling medium.
There is greater temperature uniformity throughout the freezer and the interior storage space is maximised, enabling a capacity of up to 21,600 samples.
Furthermore, all samples are maintained below the critical temperature of -130C.
Thermo Scientific cryogenic freezers feature a patented, single compressor, orbital refrigeration system with an exclusive, HFC/CFC-free mixed refrigerant.
This provides a reduced operational cost when compared with liquid-nitrogen alternatives.
The evaporator design also increases the effectiveness of the refrigerant flow, as well as the removal of heat from the cabinet.
