  • 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, safely below the -130 C glass transition temperature
  • Manual defrost
