索取COA

  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. 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. 

  5. Are Davisil series 710 silica gels heat activated?  What does "NW" in supplier name for product "Davisil Grade 710NW" refer to for product 236756?

    All of our Davisil silica gels are heated to dry just prior to packaging.  However, silica can easily pick up moisture when a container is opened.For any water sensitive applications, this is what we recommend:  Prior to use, to get rid of free water from the silica gel, dry the silica at 180°C for a few hours (e.g., 3 hours) in a drying oven. Note that at a temperature above 200°C, there will be loss of silanol groups.The "NW" is an internal Grace designation which is not necessarily related to the product other than it being a narrow particle size distribution and manufactured at a plant in Worms, Germany.
