pH Tests for Rapid On-Site Analysis


pH Papers, pH Solutions and MQuant® Strips Require Nothing Else.

pH value plays a highly important role in biochemistry, chemistry and technology. It affects numerous chemical processes. The results of many analytical methods are influenced by the pH of the solvent or buffer. The measurement can be made with a pH meter or with rapid tests, such as pH indicator paper or strips and pH indicator solutions (pH indicator mixtures).

Research or industry – no matter what Cho chooses when she graduates, she's sure to find MilliporeSigma´s pH test strips and papers waiting on the desk, just as she did when she was in college. 

Five Advantages of Rapid Tests

pH indicator papers, MQuant strips and solutions for rapid on-site analysis
  • they can be used directly on the spot
  • no additional aid or sample preparation is required
  • the results are available within seconds
  • they are high-quality standard thanks to the use of primary reference materials from NIST and PTB
  • calibration and checking using certified buffer solutions

The highly accurate results enable the user to take any necessary countermeasures immediately – in environmental analysis as well as in the industrial sector as part of in-process controls. MilliporeSigma offers you a large number of products for pH measurements with different methods of operation: various pH indicator papers, MQuant® pH test strips, and pH indicator solutions.

pH Indicator Papers are the Classical Choice

pH indicator papers – the classical choice for quick on-site pH tests pH indicator papers by MilliporeSigma are well suited for long-term storage. Supplied in rolls, they are well protected against external influences such as moisture, light, and acid and alkaline gases.

pH indicator papers are manufactured by impregnating high-quality filter paper with indicator or mixed-indicator solutions. Then the paper is dried, cut and packed into the corresponding sizes.
