CW/24.20.721 for medium range CW/24.20.722 for high range Please note: As of April 2021, the packaging of the tubes has changed and they now feature a round bottom.

Dichromate - The dichromate method is adapted from the standard EPA and ISO methods for determination of COD, which are approved to measure COD concentrations ranging up to 1500 mg/L O 2. For samples with expected concentrations in the high range of 0 to 15000 mg/L O 2 , the dichromate reagents can be used for accurate COD determination.

HI93754G-25 COD Medium Range Reagent Vials, ISO Method (25 tests) The HI93754G-25 are reagent vials that follow the ISO approved method for the medium range determination of chemical oxygen demand (COD) using a compatible benchtop photometer.

Details of Chemical Oxygen Demand Test: 2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours. The orange Hexavalent chromium is reduced to a greenish trivalent chromium.
