Hanna Instruments HI7004L 4.01 pH Calibration Buffer Solution, 500mL Bottle Review

This solution in needed to calibrate your pH meter electrode.

Lab chemicals reagents - just like HP/other brand printers the manufacturer gets you in the wallet when it's time to replace lab supplies (like the printer example - consumable toner/ink/special photo paper).

This is the Hanna OEM replacement and work as advertised. The performance is fine, just wish the prices of Hanna replacement reagents/suppliers were ~50% lower. A non-proprietary solution costs half the price.

Amazon shipping was prompt.
