Good value for pH references
These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up.

Works and seems to be an accurate reference material.
My only gripe is that it smells very strongly of wintergreen. Your instrument will smell of wintergreen even after you rinse it, meaning something is left coating your sensitive and highly expensive ph meter. This doesn't seem to impact performance however. And other reference materials are not as fairly priced, so its a good buy. My bottles arrived leak-free and were packaged well. I would reccomend this product as long as you can stand the minty-fresh smell that hangs around on your instrument for several days. Atleast it smells fresh i guess!

A must-have!!
Bought this for my Apera Ph60 pen!! I love using this stuff over the buffer powder!! Seems WAY more accurate!! Quicker reading in my opinion!! Super easy to use!! Everything arrived safely with no leaks! Thank you very much!!

great for the class room or plant pH control
Some plants need specific pH water to thrive. I use this to balance the number to where I want. ofcourse youll want to be in the lower ranges but they work great. Containers are well built and dont leak. I checked the pH with some strips and the levels were bang on. I thought for the price it was worth it.

Amazon package was fine .. the apera box was fine that everything came in.. but the calibration 10.1 bottle was open an leaked about 3" down.. the 4.0 bottle was down 2" and the 7.0 bottle was down and inch from top. Only bottle that was sealed was the storage liquid ... not happy, not ordering from flamingo again

All lids not tightened. Storage solution lid really loose; seal broken causing liquid to escape and run down the bottle, crystallizing around mouth and down sides. Noticeably lower liquid volume in bottle.
