Thermo mechanical Cryogenic Freezer – longtime storage of biological samples and has uniform temperatures ranging from -140ºC og -150ºC without LN2

Key drivers for mechanical Cryogenic Freezer over LN2

  • Health and safety
  • Need for low O2 monitoring / dual staffing
  • Cost of LN2 (esp. in auto-fill LN2 vessels)
  • Cost of manual handling / refills – even on auto refill LN2 vessels
  • Access to stores / LN2 fill point
  • In many cases, especially due to the cost of above, Mechanical Cryo is overall cheaper to operate
  • According to scientists, liquid phase storage provides a route for cross contamination
  • Better temperature uniformity in mechanical cry than vapour phase cryo storage
