By NanoIntegris Technologies, Inc.
Our PureTube and IsoNanotube solutions contain dionized water, nanotubes, and a proprietary combination of ionic surfactants. PureTubes: 0.25 mg/mL. Our tubes range from approximately 300 nm to 5 microns in length. Our tubes range in diameter from 1.2 to 1.7 nm, with a mean diameter of approximately 1.4 nm. No. Our IsoNanotubes and PureTubes are purified exclusively via non-chemical means. Our IsoNanotubes and PureTubes contain less than 1% catalyst by mass. The amorphous carbon (i.e., non-nanotube) content of our IsoNanotubes and PureTubes is less than 5% by mass.
NanoIntegris Launches higher-performing Ultra High-Purity Single-Walled Nanotubes: IsoSol-S100 TM Raymor-NanoIntegris breaks a new barrier by becoming the world's first company to commercialize ultra high-purity, polymer-wrapped, semiconducting carbon nanotubes dispersed in organic solvents: IsoSol-S100 TM. This innovative product, offered in powder or solution form, is the first semiconducting single-walled carbon nanotube material on the market with purities exceeding 99.9%. IsoSol-S100 has the following properties: - Can be readily dispersed in a variety of organic solvents such as toluene and xylenes. - Polymer/nanotube ratio can be adjusted to less than a factor of four with nanotube concentrations 10X higher than our aqueous dispersions. - Displays a 50% greater shelf life, as compared to aqueous surfactant solutions. - Allows the production of printed transistors with current ON/OFF ratios on the order to 1.8×10 6 and mobilities on the order of 30 cm 2/(Vs) - Is perfectly-suited for commercial ink jet and aerosol jet printing. IsoSol-100 is based on an RF-plasma grown carbon nanotube source material supplied by Raymor Nanotech at industrial scale. The IsoSol-S100 solutions can be produced at far higher production capacity than density-gradient centrifugation (DGU) or chromatography-based production techniques and at a lower cost. The highly graphitized starting material and low sonication intensity utilized during the extraction process minimizes damage to the nanotubes, allowing the material to exhibit higher crystallinity and longer average lengths of 2µm, as compared to aqueous surfactant-wrapped nanotubes. The patent-pending polymer-wrapping technique used by Raymor-NanoIntegris was developed by the National Research Council Canada within the Printable Electronics Program. It takes advantage of the selective affinity of conjugated polymers for semiconducting carbon nanotubes and surmounts the capacity bottleneck presented by competing technologies. The IsoSol-S100 material is now available to the academic community and to leading companies working in the field of printed transistors, nanotube-based electronics, and sensors.

Raw | <35% wt% | 0.8 – 1.2 | ~100 – 1,000 nm We currently offer our HiPco Raw nanotube products in two forms: Fluffy Powder and Wet Cake. Due to safety concerns with handling the extremely low-density raw material, the HiPco Raw product is provided as a wet cake for orders of greater than 5g unless otherwise requested. The wet cake is roughly 10wt% nanotubes. The remaining mass is a mixture of 10% ethanol and 90% water, which can be easily removed by thermal or centrifugal treatment. (e.g. 10.70g of wet cake will be provided for a 1g HiPco Raw SWNT order.
