Traceable Biopharmaceutical Calibration Solution Standards Review

Buffer comes with NIST documentation and expiration date printed on bottles. The pH values are given at 20 and 25°C. The product seems comparable to what you would get from Fisher Scientific etc but a few bucks less.

I use this solution to calibrate all my various pH meters and it works as expected. Solutions - precise bodies. I have not attempted to use this to calibrate any of the meters I have, which requires slightly different pH readings than those included in the kit.

Buffer pH 7.00 arrived in a leaking bottle. Luckily the bottle was sealed in a plastic bag to protect the packaging from getting wet with buffer fluid. Nevertheless, the arrival of the calibration buffer in such a dirty state was very disappointing.
