Isotech Model 459 Cryostat

• Temp range: -112 to 292°F (-80 to -180°C)
• Absolute stability (over 30 minutes):
  • ±0.005°C at -80°C
  • ±0.0015°C at 150°C
• 560mm immersion depth
• 120mm neck diameter
• 35 liter nitrogen capacity

The Isotech Model 459 Cryostat comprises an insulated machined copper equalizing block inside an 80mm diameter
tube 480mm long, attached via a flange to a lid, giving access for three thermometers, a vacuum port, and a Lemo
connector for the temperature sensor and heater. A cable runs to a controller, which sets the temperature. An
RS422 connector permits the calibration to be automated using one of our Software programs.

The Model 459 uses a controller and heater which allow the 459 to be set at any temperature above liquid nitrogen
temperature. When the Cryostat is immersed in liquid nitrogen it cools to approximately -319°F (-195°C).
