By constantly carrying out research, we strive to provide the analytical-grade carbon materials at a very competitive price. As scientists who have been working with carbon materials for years, we clearly understand the cheap costs of the original reactants and precursors and we believe the final products should reasonably stay low as well. Cost-effectivity and reproducibility are our key advantages when compared with other suppliers. Our analytical carbon materials include graphene on silica substrates, single-walled carbon nanotubes, monolayer graphene oxides, and multi-walled carbon nanotubes.
