GE Whatman® Reel Specialized Test Papers

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.
