60 mL BOD Btl, Spcl, Gls Rob Stpr-WTN 227494-99

These 60 mL BOD bottles are used for incubating diluted samples of sewage, sewage effluents, polluted waters and industrial wastes to determine the amount of oxygen required during stabilization of the decomposable organic matter by aerobic biochemical action. Interchangeable ground stoppers are tapered to prevent air entrapment. Bottles have a flared lip for water seal. A white marking area on the bottles makes it easy to identify samples.
