What is a BOD Incubator and why is it used in laboratories? A BOD incubator (Biochemical Oxygen Demand incubator) is a specialized laboratory device designed to maintain a constant temperature for the incubation of biological samples. It is widely used in microbiology, environmental science, and pharmaceutical labs to test water and wastewater samples, especially to measure the biochemical oxygen demand over a specific period. These incubators typically operate at low temperatures, usually around 20°C, ideal for simulating environmental conditions. By providing precise temperature control, a BOD incubator ensures accurate and reproducible test results. This equipment is crucial for assessing water pollution levels, supporting research, and maintaining compliance with environmental regulations. Reliable and efficient, it plays a key role in quality control processes.
