The length of graphite rod electrode can be cut freely

Graphite rod distinction: good graphite rod shines! High hardness! High purity graphite rod has higher purity and density than ordinary graphite rod, with carbon content of 99.99% and gray scale of 0.01%. It is widely used in electrodes for spectral analysis, laboratory electrolysis and spark electrodes
