Ted Pella Carbon Rods, Grade 1 Spec-Pure, 1/8″ x 12″ (3 x 304mm), Pkg/12
Grade 1 Spec-Pure Carbon Rods
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 nominal diameter = 1/8″ 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. Density 1.10 g/cm³, resistivity 67 µΩm, hardness 32 shore, and porosity 29%.
