Great value and a nice size that won't expire before I use it all. Solutions were accurate and came with certificates. pH 10 buffer read 0.02 higher than indicated on paperwork, but the 10 buffer is the hardest to keep stable and needs to stay fresh, so that's not bad. Other pH 10 buffers I have received have been off by as much as 0.45. These will be my go-to pH buffers if the price remains this reasonable.

I am a chemist working in my own small lab. I like the size of standard solutions, very well packed with certificate of analysis for each standard. I do not use much of the standard so I am expected to have them until expired. However, I hope this product is available in case I need to buy them again. I highly recommend this product for calibration or standardization of pH meter.
