Demonstrate the nitrogen cycle with Indigo® 0-100 ppm ammonia test strips. Visualize ammonium oxidation to nitrate in classroom or lab experiments.

Indigo® Instruments 0–100 ppm ammonia test strips provide a fast, safe, and visually engaging way to demonstrate the nitrogen cycle in classrooms and laboratory settings. Students can observe changes in ammonia concentration as part of experiments illustrating nitrification, including the biological conversion of ammonia (NH3) and ammonium (NH4+) to nitrite and nitrate. The simple color-change format eliminates the need for liquid reagents or glassware, making these test strips well suited for hands-on instruction, teaching labs, and outreach demonstrations that connect chemistry, biology, and environmental science.

We've been selling ammonia test strips since 2014. Buy fully documented Indigo® ammonia test strips, 25 strips/vial, with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Learning Outcomes by Discipline

Discipline Learning Outcomes / Key Features
Chemistry Illustrate oxidation of ammonia to nitrate as a redox process and connect chemical reactions to environmental cycles.
Biology Demonstrate the role of nitrifying bacteria in nutrient cycling and ecosystem balance.
Environmental Science Model eutrophication and water-quality impacts from excess nitrogen compounds.
Education / STEM Outreach Design inquiry-based experiments aligning with sustainability and pollution-prevention themes.

Best Practices

  • Prepare simulated environments: aquarium water, compost leachate, or soil slurry.
  • Measure ammonia at time 0, 24 h, and 72 h to observe decreasing concentration.
  • Pair with nitrite and nitrate test strips to complete the nitrogen-cycle sequence.
  • Encourage students to plot results and interpret biological rate trends.
  • Dispose of samples responsibly to model good environmental practice.
