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).
