Works as expected
I use this buffer along with the 4 to calibrate my digital pH meter and it works great. Does what is supposed to do.

It works...
I needed the solution to calibrate my PH water meter and it does the job. Since it doesn't require much solution to calibrate and the calibration isn't frequent, I have enough to last for a while.
