Hanna Instruments HI93754C-25 COD High Range Reagent Vials, Dichromate Method (25 tests)

The reagent vials designated as HI93754C-25 use the dichromate technique to determine COD at high ranges using a suitable tabletop photometer. These top-notch chemicals are produced in our cutting-edge facilities, and each box is clearly marked with the lot number and expiration date for traceability.
  • Pre-dosed chemicals for simplicity
  • comes with a quality certificate
  • marked with the batch number and expiration date for traceability
The HI93754C-25 COD kit comes with 25 vials that are pre-measured and ready to use. These premium chemicals use a modification of the dichromate method to determine COD. This approach calls for a hot digestion to oxidize the sample’s organic components. Hexavalent chromium in the reagent is converted to trivalent chromium during digestion. Then, using colorimetry, the amount of decreased chromium is determined. A suitable photometer measures the color intensity, and the COD content is shown in mg/L (ppm) O2. The predicted range for these reagents to be utilized with samples is 0 to 15000 mg/L (ppm) of oxygen.
The user only needs to add a little amount of the sample because Hanna vials already have a pre-dosed amount of reagent. Pre-dosed vials drastically cut down on test preparation time and eliminate the need for labor-intensive reagent preparation or glassware cleaning. The COD reagents’ vials and caps are made to prevent unintentional reagent leaks. The quantity of chemicals used and the handling time are reduced as a result of the pre-dosed reagents.
