Description
The HI774-25s are high-quality reagents that are pre-measured, allowing users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker HC. These reagents follow the ascorbic acid method in which the reaction between the phosphorus and the reactants causes a blue tint in the sample. By simply adding the HI774-25 reagent pack to the sample, the reaction will take place and the HI774 will determine the concentration from the color being produced. The results will be displayed in ppb of phosphorus. These reagents are designed for use with samples that have an expected range of 0.00 to 0.90 ppm phosphate.
The HI774-25 are the replacement reagents for the HI774 Phosphate Ultra Low Range Checker HC. 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 package for traceability.
