WebBiological Oxygen Demand Bottles. Bottles for BOD (biochemical oxygen demand) are used for the five-day BOD or BOD5 test process that incubates samples at less than 20°C (68°F) to determine the amount of organic compounds present. Bottles for BOD are designed so that a solution filling the bottle will push all air out from the bottle. WebThe Biochemical Oxygen Demand (BOD) is the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given sample at a certain temperature over a specific time period. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of …
