HI-3833-050 Replacement reagents for Phosphate

There are enough reagents for approximately 50 tests to be used with Hanna’s test kit. These high quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.

The HI-3833-050 are high quality reagents that are pre-measured, allowing for 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 coloured complex to form; the greater the concentration, the deeper the colour. A colour comparator cube is included for an accurate, side-by-side, visual analysis to determine phosphate concentration. These reagents are designed to be used with samples that have an expected phosphate range of 0 to 5 mg/L (ppm) PO₄^3-.
