Ordering Instructions and Help

Due to the hazardous nature of many of the products we sell, all requests to order / request quotes on-line are reviewed to verify that you are part of an organization that is an existing Sigma-Aldrich customer.

If your organization has not ordered from us in the past, and you wish to place an order, please contact your Local Office directly so a new account can be established or fill out an on-line My Profile form to request access to the site
