  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. 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.

  4. 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.

  5. Are these nanotubes, Product 652512, open or close-ended?

    According to the manufacturer, most of the ends are open.

  6. 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.

  7. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
