The COD Digestion System is a high-performance laboratory apparatus designed for the rapid and accurate digestion of samples to determine Chemical Oxygen Demand (COD) in water and wastewater. This system simplifies the preparation of samples using closed reflux, colorimetric, or titrimetric methods by providing precise temperature control and uniform heating, ensuring reliable and reproducible results. This device typically uses pre-filled COD reagent vials and operates by heating samples at 150 °C for 2 hours, following standard methods such as USEPA 410.4, ISO 15705, and Standard Methods 5220D. It can digest multiple samples simultaneously (commonly 6, 12, or 25 positions), and often includes features like digital timers, PID temperature controllers, and built-in safety systems. Modern systems may offer automatic shutdown, audible alarms, and chemical-resistant construction, making them ideal for environmental labs, wastewater treatment plants, and educational institutions.
