pH Tests

pH plays a highly important role in biochemistry, chemistry and technology since 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 stripsor paper or strips and pH indicator solutions (pH indicator mixtures). The great advantage of EMD Millipore’s rapid tests is that this method of determination can be used directly on the spot without requiring any additional aids or sample preparation. The result is available immediately! The high accuracy of the results enables you to take any necessary countermeasures immediately, no matter whether in environmental analysis or the industrial sector as part of in-process controls.

Analyses within seconds!

The Advantages of pH Tests by EMD Millipore:
  • Rapid pH measurement directly on site
  • High-quality standard thanks to the use of primary reference materials from NIST and PTB
  • Calibration and checking using certified buffer solutions
  • Quick results for environmental analysis and in-process controls

pH Indicator Papers – The Classic Solution!

pH indicator papers supplied in rolls are better suited for long-term storage, since they are 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. 

MColorpHast™ pH Indicator Strips – All-Around Versatility

Indicator strips contain special indicator dyes that are covalently bound to the cellulose of the reagent strip.
 

The characteristic features of the EMD Millipore MColorpHast™ pH indicator strips:
  • No bleeding of the indicator substance
  • Faster and more reliable pH measurement with the SafetyEdge Box
  • No contamination of the medium under investigation
  • Can be left indefinitely in the test medium
  • Highly accurate, even with weak buffers
  • Clearly distinct color differences between the individual pH ranges
  • Faithful reproduction of the reaction colors thanks to lacquer-based printing inks
  • Long, stable plastic strips protect the user's fingers
  • Measurement also possible in weakly colored and turbid liquids
