Top Amazon Reviews


  • Great ph calibration fluid
Great PH calibration fluid. Works well with my blue lab PH tester pen!
Reviewed in the United States on March 7, 2021 by Heather Wright

  • 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.
