Specifications

The Dual Filament Cell evaporates materials with medium vapor pressure. To prevent material condensation, an additional heating unit with an extra thermocouple is installed near the orifice. This allows independent adjustment of the orifice temperature and the main temperature of the effusion cell.

Options:
  • DFC made from molybdenum
  • Downward looking | Face-down version
  • DFC with flip-shutter
  • Multiple cells
