Product Details

Our Thermo Scientific cryogenic freezers maintain a uniform temperatures of -140°C, safely below the -130°C glass transition temperature of water. Cell viability is improved because biologically relevant, thermally driven reactions are not known to occur.

In the images above you will see a comparison of temperature distribution in a liquid nitrogen freezer (vapor phase) and mechanically refrigerated cryogenic freezer (i.e. our freezers). The graph represents temperatures at relative locations within the chamber. Data suggests 100% of the storage space maintains uniform storage temperatures safely below -130°C, while temperature in LN2 vapor system is dependent on storage location.

Our cryogenic freezers are designed for long-term storage of biologicals at uniform temperatures of -150°C without LN2 as a cooling medium

Top-to-bottom temperature uniformity is dramatically improved when compared to LN2 vapor

Lower operating costs than LN2 freezers of smaller capacity

100% of the interior space is usable, with stored samples maintained below critical temperatures

Ample interior volume with capacity of up to 14,400 samples (2mL vials in boxes)

Revolutionary, single compressor, orbital refrigeration system designed for cryogenic storage

Specially mixed, CFC/HCFC-free refrigerants maximize cooling and minimize environmental impact

Downfeed evaporator provides efficient refrigerant flow for a higher system efficiency and a better cabinet temperature uniformity

Washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal

Comes standard with RS232 output and access port on rear of unit

Microprocessor control system with touchpad data entry and digital display allows for intuitive operation

Set point security system for main power and alarm locks in temperature and alarm set points for increased sample protection

Incident monitor provides visual and audible warnings of system abnormalities for increased sample protection
