Cressington 108A Carbon Coater

The Cressington 108A Carbon Coater is typically used for coating SEM samples with less than 20nm uniform coating of conductive carbon. Once pumped down to operating vacuum pressures, a high current is passed through 2 carbon rods. An arc will occur at the point which the 2 rods touch and result in a sputtering-type deposition of carbon. The process, including pump-down, deposition and vent requires approximately 1 minute.
