Liquid Helium and Liquid Nitrogen Cooling Stages

To better understand electronic and electric materials, cryogenic or temperature-dependent studies are monitored using helium and liquid nitrogen stages.


  • Stabilization of beam-sensitive materials under high beam currents
  • Low-temperature phases can be analyzed
  • Improved spectroscopy and imaging, mainly for cathodoluminescence (CL)

Liquid Nitrogen Cooling Stages C1001, C1002, C1003

  • Nitrogen gas cools stages to less than −185 °C
  • Straightforward installation/removal permits the utilization of standard SEM stage
  • Quick cool down and stable temperatures are ensured by efficient thermal design
  • Higher upper-temperature options allow more flexibility in experiments
  • Vibration due to boiling of LN2 is removed by the external liquid nitrogen heat exchanger
  • High-precision control through temperature sensor and integral heater 

Liquid Helium Cooling Stages CF302, CF302M

  • CF302M — a helium-cooled stage module — attaches to the SEM goniometer and requires more care than the CF302
  • Complete replacement SEM stage and door assembly with X, Y, and Z axis manual micrometers
  • Exclusively engineered vibration and low drift, while reducing the consumption of liquid helium
  • Depending on the configuration and intended use, an optional radiation shield can be included
  • Complete system includes top fitting with bladder and valve, flexible transfer tube storage vessel, gas flow pump, gas flow controller, and digital temperature controller 


Dual Fuel Option

  • Works by forcing cold nitrogen gas through the circuit that is similar to the successful C1002 product
  • Allows operation of liquid helium cold stages with both helium and nitrogen

Accessories — Anti-Contaminators

  • Anti-contaminators C1005, C1006, or C1007 are included as accessories
