Edwards 306 Vacuum Coater (Carbon Evaporator)

Flat and polished samples for SEM and quantitative EDX microanalysis are usually coated with a thin conductive layer of evaported carbon. The carbon is evaported under high vacuum by resistive heating using short bursts of current from a 30V/30A source being passed through a pair of pointed graphite rods that are pressed together. Evaporation of metals such as Cr, Ag, Au and Al is also possible with the Edwards unit.

Specifications

  • High vacuum (diffusion-rotary) pumping system
  • High quality thin carbon coats using pure graphite rods
