The VISOCOLOR ® SCHOOL reagent case is especially designed for schools and caters to the needs of both students and teachers. All reagents are approved to be used in schools in Germany (GUV-SR 2004 directive) and can be disposed of easily just down the drain without any harm to the environment. The case contains 6 colorimetric and titrimetric tests for at least 50 determinations each to determine the most important water parameters:
Ammonium 0.2–3 mg/L NH4+
Nitrate 1–90 mg/L NO3–
Nitrite 0.02–0.5 mg/L NO2–
Phosphate 0.5–15 mg/L PO43–
pH 4.0–9.0
Total hardness 1 drop = 17.8 mg/L CaCO3

The newly developed tests are based on our proven VISOCOLOR ® system and were developed as high-quality VISOCOLOR ® SCHOOL test specifically for schools.
