Description
The HI93754B-25 reagent kit is designed for medium range COD measurement (0–1500 mg/L O₂) using the EPA-approved dichromate digestion method. During hot digestion, organic compounds present in the sample are oxidized, converting hexavalent chromium to trivalent chromium. The reduction is then measured colorimetrically with a compatible photometer, and the COD concentration is displayed in mg/L (ppm) O₂. This method ensures accurate and reliable determination of organic pollution levels in wastewater and environmental samples.
Each kit includes 25 pre-measured vials containing approximately 3 mL of pre-dosed reagent, significantly reducing preparation time and minimizing chemical handling. The vials are white color-coded for identification and designed with secure caps to prevent accidental leakage during digestion. Every box is labeled with a batch number and expiration date for full traceability and is supplied with a quality certificate. The pre-dosed format eliminates the need for manual reagent preparation or glassware cleaning, improving safety, efficiency, and consistency in COD testing.
