        The certificate of analysis can be printed out from this product page once the standards are received. You simply enter the lot code into the "certificate of analysis" box on the page.

    • Q:

      Can I reuse the solution after calibration (i.e)solution poured out of buffer pack? If so, how many times can I use?
      Asked on 3/1/2011 by Mahesh from UK

      1 answer

      • Staff Reviewer

        A:

        We only suggest using the buffer once once it has been poured into a separate container, and used immediately. Calibration solutions should be kept closed when not used.

    • Q:

      The CofA for the pH buffers specify a "Shelf Life" for an unopened container. What is the recommended "Shelf Life" after the container has been opened?

      • STAFF EXPERT

        A:

        For OAKTON pH Buffer Solutions (in both bottles and pouches): pH 1.68 , pH 4.01, and pH 7.00 all have an expiration date of 24 months from date of manufacture. pH 10.00 has a shelf life of 18 months from date of manufacture. And, pH 12.45 has a shelf life of 12 months from date of manufacture.
        This information holds true for opened bottles too.

      As a field service technician, is easier to transport than the gallon jugs, less wastage and multiple small containers always ensure fresh solution. Have recommended product to many of my clients

        While conducting routine testing, I noticed I did not have enough buffer solution to calibrate my ph/ec probes for the samples required for the week. I placed an order for more and it was here quicker than expected. Thank you. I'll be back...
