Scale
NanoIntegris has achieved over a 10,000x increase in production capacity since 2007. We are working to further increase our output and reduce our costs to serve the needs of our customers and collaborators
Versality
NanoIntegris’ separation technology is compatible with all established CNT synthesis methods (e.g., CVD, arc discharge, and laser ablation). It is also compatible with tubes of a broad range of diameters and lengths.
Purity
An additional benefit of NanoIntegris’ separation technology is that it efficiently removes the metal catalyst and amorphous carbon impurities which occur naturally in as-grown CNTs.
