      A:

      Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. You can utilize a buffer such as this to calibrate a pH meter in order to ensure the accuracy of that meter against a known standard.

    • 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.
