PELCO^® Double-Pointed Carbon Rods - Grade 1

All pointed carbon （graphite） rods are made from spectroscopically pure （impurities <2ppm, no element more than 1ppm） graphitized carbon. Trace elements can be Si, Al, Fe, Mg, Ca or B （less than or equal to 1ppm）. Pointed carbon rods give improved evaporation procedures and enable consistent carbon coating.

所有尖头碳（石墨）棒均由光谱纯（杂质<2ppm，无元素超过1ppm）的石墨化碳制成。 微量元素可以是Si，Al，Fe，Mg，Ca或B（小于或等于1ppm）。 尖头碳棒提供改进的蒸发程序，并实现碳涂层。
