Product Overview

HI94758A-50 is a reagent adapted from EPA Method 365.2 and Standard Methods for the Examination of Water and Wastewater (20th edition, 4500-P E) for the determination of reactive phosphorus using a compatible HI83224 benchtop photometer. These high-quality reagents are produced in our state-of-the-art facilities and every box is clearly marked with the lot number and expiry date for easy traceability.

These high-quality reagents follow an adaptation of EPA Method 365.2 and Standard Methods for the Examination of Water and Wastewater (20th edition, 4500-P E, ascorbic acid method). In this method, the reaction between orthophosphate and the reagent causes the sample to turn blue. The amount of phosphorus is then measured colorimetrically. The colour intensity is determined by a compatible photometer and the concentration is displayed in mg/L (ppm) of phosphorus. These reagents are designed for samples with an expected phosphorus content range of 0.00 to 1.60 mg/L (ppm).

Key Features

• Pre-formulated reagents: easy to use
• Certificate of quality: certificate of quality provided
• Traceability: marked with expiry date and lot number for easy traceability
• Ready-to-use vials: Hanna vials contain pre-formulated reagents, so users only need to add a small amount of sample as a blank and then add the powder reagent to measure the concentration. With pre-formulated vials, test preparation time is greatly reduced, and there are no time-consuming reagent preparation procedures or glassware cleaning. The vial and cap are designed to prevent accidental reagent leakage. Thanks to the pre-formulated reagents, the amount of chemicals and the handling time are also minimised
• Barcode identification system: these vials are equipped with Hanna barcode identification system, which is unique to the HI83224 benchtop photometer for wastewater treatment. The instrument scans each vial to automatically identify the sample method and range. The barcode has four digits: the first two are used for parameter identification and the last two for the reagent lot ID. Vials with different methods can be distinguished by the barcode printed on the vial and by the cap colour

Packing List
