  • Cryogenic temperature controller for volumetric sorption analyzers
    Patent number: 10222312
    Abstract: A cryogenic temperature controller assembly includes a controller and a thermostatic block that has a chamber for receiving a sample holder therein. The thermostatic block has a heat sink with an exposed surface for exposure to a cryogenic fluid. A heater is disposed intermediate the exposed surface and the chamber. The heater is connected to the controller. A temperature probe is disposed in the thermostatic block. The probe is connected to the controller. The controller regulates the heater based on an actual temperature from the probe to maintain a predetermined set point temperature in the thermostatic block.
