Cytiva Whatman Reel Specialized Test Papers

• Cytiva's Whatman offers a range of pH indicator and test papers to meet specific needs
• These high-quality products combine ease-of-use with unsurpassed accuracy and consistency
• The convenience of using indicator papers for the rapid determination of pH values has led to many applications in laboratories and in industry

• Convenient and portable for field use
• Accurate for a wide range of routine pH testing
• Instant pH readings
• Inexpensive

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. Cl2, 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

Phenolpthalein Test Paper:
• This white paper changes to pink at pH 8.3 and becomes red at pH 10
• It is useful for the determination of the neutralization point in weak acid/strong alkali reactions
