  • Compact design minimizes space requirements while maximizing storage capacity.
  • System is suited for both manual and computerized inventory record-keeping methods.
  • Super-insulated vessels have special, narrow-mouth design that conserves liquid nitrogen by minimizing evaporation.
  • Samples are stored below -180°C, even when less than 2 in. (5cm) of liquid nitrogen remains in the vessel.
  • Ultrasonic Level Monitor safeguards irreplaceable samples with minimal liquid nitrogen evaporation and conduction.
  • Advanced vacuum insulation minimizes liquid nitrogen evaporation and reduces operating costs
  • Optional monitor provides continuous LED readout of liquid nitrogen level; activates visual and audible alarms when level falls below safe range of approximately 1 in. (2.5cm).
  • Optional alarm also alerts operator in the event of excessive liquid nitrogen loss.
  • Secure locking hasp prevents unauthorized entry.
