You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers. 
How are the carbon nanotubes, Product 652512, produced?
Short carbon nanotubes are produced by catalytic CVD and mechanical cutting. They are purified in liquid oxidizer.
Are these nanotubes, Product 652512, open or close-ended?
According to the manufacturer, most of the ends are open.
Where can I find more information on nanotubes and your other nanoproducts?
Our Material Matters 2.1 publication is devoted to nanoproducts and their applications. Please see the following link: http://www.sigmaaldrich.com/aldrich/brochure/al_material_matters_v2n1.pdf
Where can I find a list of your other carbon nanotube products?
Please visit the following link to find a list of our nanotube offerings: http://www.sigmaaldrich.com/catalog/search/TablePage/16376687
Do you offer a respirator that blocks out nanosized material?
The respirator cartridges we currently sell for protecting against dust and particulates are the MSA air-purifying Super Cartridges GME/P100 (Product No. Z401609 or Z401722). However, per the manufacturer, these cartridges only block particle sizes up to 0.3 µm. At this time, we do not sell a respirator that will block nanosized particles, so it is best to work in a well-ventilated fume hood.
What is the Department of Transportation shipping information for this product?
