Worked out very well for a quick pH test without having to mix a huge batch of buffer solution.

These samples provide assurance when using a meter for which they are designed to calibrate. I got a meter right out of the box which measured and displayed pH values. These samples gave an independent reference as to whether or not the meter was reading values correctly. The delivery was in good time, and the samples come in a nice little cardboard box.

Having single use sized packets of buffer solution available is a great help. Although I have bottles of buffer solution available, there are times when the single use packets are better.

I was extremely happy with my purchase of EXtech's PH 4,7,10 with rinse solution. I am confident that the solutions are accurate. I never have to worry about contaminates because the solution is premeasured in a disposable packet. The last PH calibration kit I purchased was from Bluelabs which after the first use I noticed mold growing in the PH 7 bottle. This caused my PH meter to not be accurate. I did properly store the Bluelabs kit and never put anything back into the main bottle.
