BOD bottles are suitable 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. These 300 mL capacity bottles are recommended for the five-day BOD test as referenced in Standard Methods for the Examination of Water and Wastewater, 18th Edition, 5210B, 1992. BOD bottles have a specially 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 into the bottle during incubation. The stopper joint is compatible with the probes of the leading meters for BOD and dissolved oxygen. All bottles (except 0914U63) have large, permanently screened-on marking spots. The numbered versions are supplied with bar codes for quick and accurate recording of bottle numbers. All bottles are manufactured from Type 1 borosilicate glass and feature robotic stoppers. Thomas Number 0914U63 is a standard 300 mL BOD bottle with black PVC plastic coating that blocks all visible light up to 800 nm. This inhibits the production of oxygen by algae. It is recommended for use in marine photosynthesis projects in which you need to compare oxygen in a light and a dark bottle. This bottle is supplied complete with a glass robotic stopper and an opaque black cap. To replace stopper use Thomas number 1234R63.
