Description:
Wheaton 227497-12 Glass 300mL B.O.D. Bottles with Robotic Stoppers and Bar Code Labels 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. The 300 mL bottles is recommended for the five-day BOD test as referenced in Standard Methods for the Examination of Water and Wastewater, 21st Edition, 5210B, 2005. These 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 of the BOD bottles have large, permanently screened-on marking areas. All of the bottles are manufactured from Type I borosilicate glass.
