For water quality testing

Provides an extremely clear and accurate visual pH value using four different segments of dye-impregnated indicator papers. Whatman™ pH Indicator Papers, CF Strips use dyes that are chemically bonded to the paper and cannot be leached into solution.

Used for rapid determination of pH values

Assumes a color specific to sample pH upon contact with a sample. Whatman™ Acid/alkali Test Papers are impregnated with a mixture of pH indicators.

Impregnated with a mixture of pH indicators, acid-alkali litmus papers assume a color specific to sample pH upon contact with a sample. Whatman™ Litmus Blue Test Paper provides rapid determination of pH values and has a variety of applications in laboratories and industry.
