Necessary for pH measurements

By 

from Winnipeg

Verified Buyer

Comments about Oakton Buffer pack, 500 mL each of 4.01, 7.00, and 10.00 buffer:

As a chemist I know the importance of accurate pH measurements. The best way to calibrate a pH meter is to use the three buffer standards (4,7,10). I'm using a Oakton portable pH meter to measure the pH of my hot tub water so I can then adjust the pH to between 7.4 and 7.6. The pH papers are at best a guess.

    Comments about Oakton Buffer pack, 500 mL each of 4.01, 7.00, and 10.00 buffer:

    Being mindful that these are corrosive chemicals, I was a little surprised that MSDS sheets did not accompany the product at delivery.
    Other than that, they work as they should.

    Side note: this web page sucks on my smartphone.

      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...

        • 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.
