Long Term Biologicals Storage.

  • Our Revco Ultima II cryogenic freezers maintain uniform temperatures of -140°C and -150°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.

Safer, More Convenient Than LN2.

  • Our cryogenic freezers include all features, control and performance attributes of the Ultima II Series freezers, plus many important advantages not available when using LN 2.
  • Stable cryogenic temperature of -140°C and -150°C without LN 2 as a cooling medium.
  • Patented, single compressor, orbital refrigeration system.
  • Top-to-bottom temperature uniformity dramatically improved when compared to LN 2 vapor.
  • Lower operating costs than LN2 freezers of similar capacity.
  • 100% of interior space is usable, with stored samples maintained below critical temperature.
  • Ample interior volume with capacity of up to 21,600 samples in Model ULT-10140 and up to 14,400 samples in Model ULT-7150 (2 ml vials in boxes).
  • Uses standard Thermo Scientific Revco inventory racks and fiberboard boxes.

Operating Temperature.

  • Cryonenic Chest Freezer 1 (CCF1): -140°C.
  • Cryogenic Chest Freezer 2 (CCF2): -150°C.

Refrigeration System.

  • Exclusive mixed refrigerant autocascade with a single, orbital refrigeration compressor, air-cooled.
  • CFC-free refrigerants.
  • Downfeed evaporator for most efficient refrigerant flow.
  • High-capacity air-cooled condenser with dual condenser fans, aerodynamically shaped fan blades.
  • Washable condenser filter keeps fins free of dust to maintain peak cooling efficiency; no tools required for removal.

Control System.

  • Exclusive IntrLogic microprocessor control system with touchpad data entry and digital display of all functions.
  • Setpoint security system with key-operated switch for main power and alarm locks in temperature and alarm setpoints.
  • Independent operating temperature and high/low limit alarm functions with factory-set defaults for quick start-up, all setpoints adjustable in 1°C increments.
