Wheaton BOD Bottles are ideal for incubating diluted samples of sewage, sewage effluents. polluted waters, and industrial wastes to determine the amount of oxygen required during the stabilization of the decomposable organic matter by aerobic biochemical action. We recommend the 300 ml capacity bottles for the five-day BOD test as referenced in Standard Methods for the Examination of Water and Wastewater, 21st Edition, 5210B, 2005.
These BOD bottled have a specialty designed shoulder radius that sweeps all air from inside the bottle during filling. The interchangeable stoppers have a tapered bottom that also prevents air entrapment. The bottles have a flared mouth to form a water seal around the stopper that prevents air from being drawn in to the bottle during incubation. The stopper joint is compatible with the probes of the leading 3 meters for BOD and dissolved oxygen.
All of the BOD bottles have large, permanently screened-on marking areas. The numbered versions of the 300 ml size bottles are supplied with bar codes for quick and accurate recording of bottle numbers. All of the bottles are manufactured from Type I borosilicate glass.
