pH Test Strips, pH Papers, Readers & Accessories
The pH value plays an important role in biochemistry, chemistry and technology as it affects numerous chemical processes. The results of many analytical methods are also influenced by the pH of the solvent or buffer. We offer a wide range of products for rapid pH measurements with different methods of operation such as pH indicator papers, pH test strips, and pH test kits.

Non-bleeding pH-test strips
Non-bleeding MQuant® pH-indicator strips are made of special indicator dyes that are covalently bound to the cellulose backing. This offers the advantage of being able to leave the pH-indicator strips in the testing media for an indefinite time, which yields accurate measurements even with weakly buffered samples. The MQuant® pH-indicator strips cover different pH ranges from the universal range of 0 to 14 or more specific ranges depending on the applications. For your convenience, we provide single-sealed test strips, tubes of 100 strips as standard unit, as well as customized packaging.
pH tests in turbid and colored solutions
MQuant® and Reflectoquant® pH test strips are utilized to measure pH in colored and/or cloudy solutions, where conventional pH-indicator strips can lead to falsified results. In these strips, the pH reaction zone is backed by a transparent carrier film, allowing users to simply evaluate the color from the back side. Particles from turbid samples and coloring substances stay on the surface of the test pad and don’t interfere with the reading of the result. The pH test strips are specially designed to deliver reliable results in turbid or colored sample solutions without additional sample preparation.
pH Test Readers
Measure pH with our free MQuant® StripScan mobile app, that digitally reads out the MQuant® pH test strip 0-14 in seconds. The app analyzes the test strip using the phone camera along with a color reference card. The results generated can be effortlessly managed, visualized and shared with the StripScan Web dashboard application.
Additionally, we provide test strips with batch-specific calibration that can be used with our portable, easy-to-use Reflectoquant® RQflex®20 reflectometer for your laboratory quantitative pH measurement.
pH Test Papers & Kits
We have a range of classic pH-indicator papers that are made of high-quality filter paper impregnated with an indicator or mixed-indicator solutions. Browse our portfolio of various MQuant® pH-indicator papers to find the perfect product for your application.
For clear and slightly colored samples, we provide MQuant® liquid pH-indicator test kits that are well suited for measurements in drinking water, boiler water, wastewater, surface water, aquarium water, swimming-pool water, and testing soil samples. Further, in case of strongly turbid or colored solutions, the samples can be made colorless and clear by filtration or treatment with activated charcoal for pH measurement.
