Product Description In contrast to conventional indicator papers the indicator dyes of pH-Fix sticks are substantively bound to the cellulose fibres (DE-PS 24 36 257). As a result the possibility of the colour bleeding, even in strongly basic solutions, is avoided. Directions Dip the pH-Fix stick into the solution to be tested. Remove the stick and compare the color to the provided color chart to determine the pH value. The pH range for this product is 7.5-9.5. For accurate results, do not submerge the stick for an extended period to avoid color bleeding. This product is suitable for chemistry experiments, water testing, and quality control in manufacturing processes.
