What is a BOD incubator and what is its primary purpose?

A BOD (Biological Oxygen Demand) incubator is a specialized laboratory instrument designed to provide a controlled temperature environment, typically around 20°C, for microbial and biochemical studies. Its primary purpose is to measure the amount of oxygen consumed by microorganisms in a water sample. This measurement indicates the level of organic pollution in the water. The device also supports a wide range of other microbial and pharmacological testing.
