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. WebBOD5. The 5 day biochemical oxygen demand, or BOD5, is water quality parameter. BOD5 measures the quantity of biodegradable organic matter contained in water. This biodegradable organic matter is evaluated using the oxygen consumed by the …
