SPI Brand Modular System with Carbon Rod and Fiber Heads.

This SPI brand modular evaporative coater uses high tempaeratures to evaporate carbon rods, filaments or a variety of metals (almost any metal with a boiling point lower than the melting point of the tungsten baskets that hold the coating material.) This technology uses a low voltage (1-10V) but a very high current (10-30 Amps) to create a vapor of coating material (contrast this with the plasma coater). The coating produced by this coater is intended to reduce sample charging caused by electron bombardment.
