Chemical Oxygen Demand Reagent Vials

CHEMetrics (USA) offer an economical line of reagent vials for performing chemical oxygen demand (COD) measurements. Chemical Oxygen Demand (COD) measurements are frequently performed in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater.

For the lab currently using the micro-COD reactor digestion method, the CHEMetrics COD reagent vials achieve excellent results and reduced operating costs, without the need to modify existing equipment or procedures. Contained in a sturdy, environment-friendly biodegradable package, the vials feature optical-quality glass for accuracy, Teflon®-lined screw caps for inertness, and the standard 16-mm diameter for compatibility.

CHEMetrics offers COD products for both the EPA-approved method and a mercury-free method. To perform the COD measurement, the user simply adds sample to the vial, replaces the Teflon-lined screw cap, and heats the vial for 2 hours at 150°C. Once this digestion is completed, results are simply obtained using any photometer that accepts 16-mm sample cells. The CHEMetrics COD vials can be directly used in many instruments having pre-programmed calibrations.
