High Purity Carbon Rods

Available in 3.05 mm diameter or 6.15 mm diameter sizes (depending upon coating system). Carbon rods are typically used for evaporating (and sometimes shadowing) carbon onto specimens being prepared for either x-ray microanalysis (EDS or WDS) or transmission electron microscopy (TEM). Carbon rods supplied by Quorum are high purity - spectroscopically pure - with less than 6 ppm ash.

Carbon rods are supplied in a flat-ended format and should be shaped using the Quorum 13232 carbon rod shaper. A word of warning: do not be tempted to use a pencil sharpener as process control and quality will be poor!
