what is biological oxygen demand, BOD Bottles (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.
BOD Bottles are designed so that a solution filling the bottle will push all air out from the bottle. BOD Bottles generally include a flared mouth and glass stopper, which serves to form a tight seal that protects the bottlesâ contents from outside contamination. Typically, BOD bottles feature a permanent white writing area on the side of the bottle to aid in sample identification.
