Use Indigo® nitrate-nitrite strips to demonstrate urinalysis chemistry in classrooms. For educational purposes only, not for medical diagnosis.

Indigo® nitrate-nitrite test strips offer a simple, visual way to demonstrate the chemistry behind urinalysis in microbiology and clinical chemistry education. In instructional settings, nitrite reactions are commonly used to illustrate how bacterial metabolism can be detected through chemical indicators. These test strips allow students to observe colorimetric responses safely and consistently in controlled lab exercises, without the need for clinical reagents or instrumentation.

We've been selling nitrate-nitrite test strips since 2009. Buy fully documented Indigo® nitrate-nitrite test strips, 50 strips/vial. Guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Discipline Learning Outcomes / Key Features
Microbiology Understand how bacteria reduce nitrate to nitrite in the urinary tract; link chemical reactions to microbial metabolism.
Clinical Chemistry Demonstrate how nitrite testing is used as a preliminary UTI screening method; highlight limitations vs. confirmatory tests.
Nursing / Medical Technology Gain familiarity with strip-based urinalysis methods as part of lab training; practice interpreting results.
General Biology Explore diagnostic chemistry in human physiology; connect classroom lessons to real-world healthcare applications.

Tips for Best Results

  • Use synthetic or prepared urine simulants for classroom demonstrations.
  • Emphasize that these strips are for educational use only, not clinical diagnosis.
  • Compare strip testing with confirmatory lab methods (e.g., culture, spectrophotometry).
  • Frame exercises around limitations of screening tests and the importance of follow-up diagnostics.

Specifications

This Indigo® test strip indicates the presence of nitrate & nitrite. Results for ranges shown below can be read in 30 seconds.

  • Nitrate is measured in increments of 10, 25, 50, 100, 250, & 500ppm
  • Nitrite is measured in increments of 1, 5, 10, & 25ppm
  • The number of strips (50) vial is approximate.
  • These strips have a guaranteed shelf of 3 years from date of manufacture (indicated by expiration date).
  • These strips are extremely sensitive to airborne humidity.
  • Reseal the desiccant lined bottle immediately after removing a strip to ensure 3 year shelf life.
  • Vial must be kept tightly sealed & kept at typical room temperatures.
