Our BOD Bottles are the perfect choice for
incubating diluted samples of clean water, waste water, effluent
water, and polluted water during the 5-day biochemical oxygen
demand (BOD) test. This procedure is used to determine the
relative oxygen requirements of the tested sample. 300mL bottles
with glass stoppers are recommended for the 5-day BOD test
(Standard Methods for the Examination of Water and Wastewater).
These BOD bottles feature a flared mouth to
form a water seal to prevent the ingress of air during
incubation. The interchangeable stoppers have a tapered bottom
that also prevents air entrapment.
