pHFix Indicator Strips are plastic and, unlike conventional indicator papers, the indicator dyes are chemically bonded to the cellulose fibers. As a result, the possibility of color bleeding, even in strongly alkaline solutions, is avoided.
Measurement of pH values is possible even in unbuffered or very weakly buffered solutions, since the sticks can be left in the solution until the final color change is completed. Test samples are not contaminated by the indicator dyes.
Colors of the individual color fields cannot run into each other. This allows a more precise comparison with the color scale.
Specially developed indicator dyes guarantee a sharp differentiation between the individual pH values and a clear and easy comparison to the color scale.
Length and stability of the plastic strips protect fingers from contact with the test solution.
Economical to use each bag contains 10 test strips.
