Phosphate Test Kit Replacement Reagents (100 tests) - HI38061-100

The HI38061-100 are replacement reagents for the colorimetric determination of phosphate with the HI38061 Phosphate Test Kit. 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 HI38061-100 are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate phosphate measurements with the chemical test kit. These reagents follow the ascorbic acid method to determine phosphate concentration.

For determination of phosphate, the reagent containing ammonium molybdate and potassium antimonyl tartrate reacts in an acid medium with orthophosphate to form a phosphomolybdate complex. The phosphomolybdate complex is reduced by ascorbic acid, causing a blue 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 phosphate concentration. These reagents are designed to be used with samples in three ranges: 0.00 to 1.00 mg/L, 0.0 to 5.0 mg/L, and 0 to 50 mg/L PO43-.
