CHEMetrics Chemical Oxygen Demand Vials

The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure overall level of organic contamination in wastewater. The contamination level is determined by measuring the equivalent amount of oxygen required to oxidize organic matter in the sample. Two dichromate reactor digestion methods are available for fast, easy, safe determination of low, mid, and high range COD levels in wastewater. Requires use of photometer.
