UHV Model 218

High Performance in a Small Package with Crucible Volumes to 15cc.

  • Rated at 6kW* of power when operated at voltages from -6 to -10kV.
  • Compact design for use in small research and development systems or wherever space is an important consideration.
  • The model 218 UHV uses the same basic components as the standard model 211, with non-interchangeable crucibles and all metal sealing.
  • Coils sealed in stainless steel cans are standard

UHV Model 259

Performance Proven in High-Power Production Applications

  • Available in crucible volumes up to 100cc for long, uninterrupted evaporation.
  • Rated at 14kW* when operated at -10kV.
  • Capable of evaporating high rates of material such as aluminum. This makes the model ideal for processes that require a coating layer of one micron or more.
  • The 259 is also well suited for operation at lower power levels where a large capacity for subliming materials might be required
