The product is exactly as shown. Packed well, individually wrapped, and sealed. Made in the USA. I will use this with my Apera Instruments PH60 Premium Waterproof pH Pocket Tester. I am happy with both the Ph Calibration Buffer Solution Kit and my Apera pH Meter.

All 3 8 ounce bottles of calibration solutions and the 4 ounce bottle of 3M KCI storage solution were carefully packaged and clearly labeled. Contents, quality, and performance were exactly as described. Would recommend without reservation.

The product is working very well and calibrating much more accurately than my past order of pH buffers (pH 4 was at 4.33...), that I ended up returning. I won't need to return these this time!

Fantastic product! My pH calibration readings no longer drift all over the place like they were with the product I was using previously. Will definitely order again.

Good fluid for calibration and storage! Bought it to use with my Oakton pH pen. Glad I did!

The pH calibration kit arrived in a timely manner. It has been very helpful for calibrating my Apera PH60 meter, and is straightforward to use.
