About this item
Cytiva offers a range of pH indicator and test papers to meet specific needs.
- Convenient and portable for field use
Potassium iodide test paper: For detecting chlorine and other oxidising agents. In acid solution, oxidising agents react with the iodide in the test paper to liberate iodine. The paper turns blue in the presence of an oxidizing agent (e.g., CI₂, Br₂, H₂O₂, HNO₂ etc.).
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.
These high-quality products combine ease-of-use with unsurpassed accuracy and consistency.
