General description
pH indicator and test papers to meet specific needs, offering quality, convenience and ease-of-use. We offer a range of pH indicator and test papers to meet specific needs. These high-quality papers combine ease-of-use with accuracy and consistency.
Lead acetate test paper
Used for detecting hydrogen sulfide, this rapid qualitative test paper, when wetted with distilled water, can detect as little as 5 ppm of H2S in the atmosphere or in a gas stream. Hydrogen peroxide can be detected with this paper by preblackening the paper in H2S. Concentrations as low as 4 ppm can be detected.
Potassium iodide test paper
Used for detecting chlorine and other oxidizing agents. In acid solution, oxidizing agents react with the iodide in the test paper to liberate iodine. The paper will turn blue in the presence of an oxidizing agent (e.g. CI2, Br2, H2O2, HNO2 etc.).
Universal indicator papers
Universal indicator papers have been impregnated with a mixture of several indicators. On contact with the sample solution they assume a particular color. A check against the color comparison table supplied allows the pH to be determined.
