A COD Digestion Apparatus is a laboratory instrument used for Chemical Oxygen Demand (COD) testing, a vital process in analyzing the pollution level of wastewater and industrial effluents. The apparatus digests water samples containing organic matter using a strong oxidizing agent (potassium dichromate) and concentrated sulfuric acid at a controlled temperature, typically 150°C for 2 hours.
The Hema Scientific COD Digestion Apparatus ensures uniform heating, precise temperature control, and safe operation, providing reproducible results for environmental and industrial laboratories.
