Cytiva's Whatman™ pH Test Strips

Cytiva's Whatman™ pH Test Strips are individual plastic support strips which feature multiple colored segments of dye-impregnated pH paperindicator paper. The resulting combination of color differences gives an extremely clear and accurate visual pH value. All the dyes of Whatman pH test strips are chemically bonded to the paper and cannot be leached into solution. Thus problems associated with contamination of the sample and resultant anomalous readings are avoided. The unique combination of color change resulting from each test is compared with the color-coded comparison chart printed on the dispenser giving improved speed and accuracy in reading. Whatman pH Test Strips are available in both short pH ranges as well as wide pH ranges.
