CHEMetrics offers two dichromate reactor digestion methods (USEPA-accepted and Mercury-free) for fast, easy, safe determinations of COD levels in waste water — at about 30% lower cost than competitor's vials! Our COD Reagent Vials can be used with CHEMetrics® photometers and with spectrophotometers that accept 16 mm diameter round bottom cells.

To perform the COD determination, the analyst simply removes the Teflon-lined screw cap from the vial, adds sample to the vial, and replaces the cap. The vial is then heated for two hours at 150°C in a standard digestor block. Once digestion is completed, results are obtained using any photometer that accepts 16-mm diameter cells.
