Description. Specifications. Description. 16mm Hach vials for vials for Chemical Oxygen Demand ( COD ) determination. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport.

With CR 4200 two different digestion programs can be performed for 16 mm vials simultaneously in two seperate heating blocks for 12 vials each. • 8 stored programs for quick operation. • 8 user-defined programs from 25-170°C for high temperature digestion up to 170°C. • AQA/IQC with external temperature sensor.

5220 CHEMICAL OXYGEN DEMAND (COD)* 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled con-ditions. The quantity of oxidant consumed is expressed in terms

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.

Chemical oxygen demand (COD) is a critical waste treatment measurement in everything from municipal systems to food manufacturing waste streams. Performing COD testing the right way is important in determining wastewater treatment effectiveness and can help diagnose any problems in treatment.
