Mold growing in electrode solution.
-C•November 22, 2017
Returned do to unsanitary production methods, as evidenced by mold floating in the unopened bottle of electrode solution.
Product arrived broken and repackaged
Amazon Customer•November 4, 2017
Product works fine but package was rebagged with the electrode storage solution cracked and leaking all over the other bottles. Someone must have realized this as why else was it repackaged and put into a plastic bag over the normal cardboard box and sealed? We needed solutions for that Saturday's processing and didn't realise issue of why it was rebagged until after using other ph solutions. Good product, damaged or reused inventory.
Good Quality and Price
Dr. Terrence McGarty•June 16, 2017
Good quality, good price and fast delivery. I use these to calibrate a pH meter. They seem to be spot on and give consistent results. My desired accuracy is not that great +/- 0.25 on measurements but this seems to get my instruments to +/- 0.1. I calibrate about once every twenty five readings doing anthocyanin extraction in HCl aq.
Five Stars

These have done a great job calibrating my digital pH meter so far. No complaints.
Best Price I found... My testing kit is complete!
Marv•December 9, 2016
Best price I found for calibration solutions. Used in conjunction with the Bluelab PH & EC pens. 100% pleased with my overall testing kit
3 part kit provides increased accuracy over the 2-stage. The storage solution is great and appropriate that it comes in a smaller quantity.
Be sure to keep stored in a cool dark location, don't pour excess back into the big containers and you're good to go!
