MVE Variō Series

The completely dry sample storage area maintains a user-defined temperature anywhere between -20°C and -150°C. The MVE Variō Series cryogenic freezer significantly reduces the possibility of sample contamination via contact with LN2 while providing the safety margin and consistent temperature profile associated with LN2-based cryogenic freezer storage.


  • Approximately 70% operating cost savings compared to leading mechanical freezers (-80°C)
  • Less than 1% of the electricity consumption compared to leading mechanical freezers (-80°C)
  • Consistent temperature profile, even with the lid open
  • The available conversion kit allows the Variō to operate as a High Efficiency -190°C freezer
  • Improved processing time, minimal increase in temperature when warm samples are introduced into the cryogenic freezer
  • No thermal load: no heat introduced into the room, and no additional HVAC required.




Designed to meet the most stringent requirements, we offer quality refrigerators to store critical research material, clinical samples, and vaccines in a controlled environment ranging from 2°C to 8°C.
