  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. Who do I contact about larger solvent volume needs?

    Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com

  4. How do I know what packaging options are available for a solvent?

    The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.

  5. Who do I contact if I need a solvent blend, which you do not carry?

    Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, Visit the Solvent Center

  6. The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?

    The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, Visit the Solvent Center.

  7. Which solvent grade should I be using for my application?
