    • A:

      The previous answer is incorrect- the PRODUCT is not ISO 9001:2008 certified, the quality management system in the facility it is prepared in is. Product cannot be ISO certified.

      A:

      It is ISO 9001:2008 certified but not 17025. Please see part number 00651-32 for NIST traceable buffer made in a ISO guide 34 and 17025 facility.
