    • Works as advertised
This stuff works well and helps me calibrate my ph meters.

    • Significantly less than competing calibration buffers
A calibration solution has a very simple task, remain stable at a specific target pH. The Biopharm buffers do this at half the price of the Hanna buffers they replaced.

Great PH calibration fluid. Works well with my blue lab PH tester pen!

    • I might not understand
I bought this to calibrate my handheld pH meter. These 2 are accurate but from what I can tell most meters need 3 different pH samples (basic, neutral abd acidic) to properly calibrate them. Maybe there are some devices that only use 2 but every one I've owned requires 3.
