Carbon rods, grade 1 spec-pure, 6.15mm x 305mm

Frequency Specific High Purity Carbon Rods for Cressington Carbon Coaters. Impurity level of 5ppm or less.

Spectroscopically pure graphite structure carbon rods with an impurity level of 2ppm or less with 1ppm as maximum level for each element. Trace elements can be Si, Al, Fe, Mg, Ca or B (less than or equal to 1ppm). The rods are all 12" long with three nominal diameters (1/8", 3/16" and 1/4") to comply with the carbon source used in different high vacuum carbon evaporators. Highly recommended for TEM, FESEM, FIB, WDS, EBSD, Microprobe and more critical SEM/EDS applications.
