There are enough reagents for approximately 100 tests to be used with Hanna’s test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

  • Pre-made reagents for ease of use
  • Prepared with high purity chemicals
  • Marked with expiration date and lot number for traceability


The HI38040-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate iron measurements with the chemical test kit. These reagents follow the phenanthroline method to determine iron (Fe2+ and Fe3+) concentration.

For determination of iron, all ferric (Fe3+) ions are reduced to ferrous (Fe2+) ions before the phenanthroline reagent is added to the sample. The reaction between ferrous ions and the reagent causes an orange colored complex to form; the greater the concentration, the deeper the color. A Checker Disc is included for an accurate, side-by-side, visual analysis to determine iron concentration. These reagents are designed to be used with samples that have an expected iron range of 0.0 to 5.0 mg/L (ppm) iron.
