Ultra Pure Single-Walled Carbon Nanotubes

We provide ultra pure single-walled carbon nanotubes of smallest diameter produced from the world’s most advanced high-pressure carbon monoxide reactor. Further, Ultra pure SWNTs are purified by using acid-base treatment. As a result, most of the trace amorphous carbon the catalyst particles are removed.
