pH Test Plastic Roll and Book - Premium range

pH indicator plastic rolls and books enable quick and easy pH determination across a broad range of water-based solutions. Unlike standard pH papers that may bleed dyes into the sample, the indicators in these products are firmly bound to the paper matrix. Consequently, no colorant is transferred to the test solution, regardless of the pH value.

For this reason, they are particularly well suited for weakly ionic solutions, as they can remain immersed for extended periods without compromising either the sample or the accuracy of the measurement.
