LTEC (NTEZ) Effusion Cell  | © Scienta Omicron


Low Temperature Effusion Cells


  • Suitable for the evaporation of high vapour pressure materials and of organic materials
  • Temperature range from 80 °C to 400 °C / from 300 °C to 700 °C
  • Extremely stable flux rates
  • Various crucible sizes and crucible materials
  • Various filament configurations

The low temperature effusion cells are dedicated to the evaporation of high vapour pressure materials and of organic materials.

  • Reliable, compact and robust cell design
  • Cleanest operation in UHV systems
  • Excellent temperature stability (± 0.1 °C)
  • Optimized low temperature cell with two standard temperature ranges from 80°C to 400° C or from 300 °C to 700 °C
  • Standard, hot lip, cold lip and dual filament configurations available
  • Standard crucible sizes: 2 cc, 5 cc, 10 cc, 35 cc, 60 cc 
  • Standard crucible material: PBN (pyrolytic boron nitride)
  • Other crucible materials: Al2O3, BeO, Tungsten, Pyrolytic Graphite(PG) or Quartz
  • Effective water cooling around the cell protects both the vacuum chamber and the port tubes and avoids heating up by thermal radiation
  • Compact version with cooling shroud and integrated shutter on a DN40CF (2.75” OD) mounting flange and 10cc crucible capacity; ideally suited for small research surface analysis systems
  • Large size effusion cell with crucible capacities up to 200 cc and with separate cooling shrouds available
  • Modified low temperature effusion cells for reactive low pressure gas atmospheres (e.g. O2, N2, NH3) are available on request
