We are one member of the National Nano-sciences & Nano-technology Center of China. we have done a lot of research and development work in the carbon nanotubes synthesis and application since 1996. Now, We can produce 1.5kg SWCNTs per day and 20kg MWNTs per day. And MWNTs with purity more than 98wt% max. We are committed to supplying the nanotechnology research and industrial community with the highest quality carbon nanotubes (CNTs) at the lowest prices, believe that we are the best choice for you.
