Chest cryogenic freezers -150

Mechanical cryopreservation for long-term biological storage.
Safer, more convenient than LN2— systems. Our Thermo Scientific cryogenic freezers maintain uniform temperatures of -140° and -150°C, safely below the -130°C glass transition temperature of water.

 
Top-to-bottom temperature uniformity is dramatically improved when compared to LN2 vapor. Cell viability is improved because biologically relevant, thermally driven reactions are not known to occur.
  • Uniform temperature of -140°C or -150°C, safely below the -130°C glass transition temperature
  • Manual defrost

Refrigeration System

  • Exclusive mixed refrigerant autocascade with a single, orbital air-cooled compressor
  • Downfeed evaporator
