Cytiva offers a range of pH indicator and test papers to meet specific needs. These high-quality products combine ease-of-use with unsurpassed accuracy and consistency. The convenience of using indicator papers for the rapid determination of pH values has led to many applications in laboratories and in industry. These pH indicators have been impregnated with a mixture of several indicators. On contact with the sample solution they assume a particular color. A check against the color comparison table supplied allows the pH to be determined.

Each test strip has a central segment of indicator dye and, printed alongside, eight or more different color segments marked with corresponding pH values for matching purposes. The pH test value can be read-off by direct comparison of the test strip color and the color bars. Ideal for colored solutions, when any changes in color of the paper stock are automatically canceled out.

• Instant pH readings
• Accurate for a wide range of routine pH testing
