This stuff is good. The One Pen from Blue Labs cost too much not to buy the best products to keep it working properly. This storage solution works. I will be buying more to keep my meter safe.

Useful!
If you have the BlueLab pH pen you need this. Used to store the pH pen, this solution keeps the pen tip hydrated and in calibration. Without storing properly the tip dries out and then your readings can vary or you may need to re-hydrate and recalibrate more often. I love the pen, and it’s too bad it needs the storage solution, but it sure helps with getting good consistent readings and results !!

Bottle lasts for a long time.
I like the drip top. It only takes a couple drops at a time for my PH pen.
