Designed for sampling and incubation of aqueous samples. Determines the amount of oxygen required during the stabilization of the decomposable organic matter by aerobic biochemical action.

·         The design incorporates a flared mouth used to form a water seal which prevents the drawing of air into the bottle during incubation

·         The bottle’s shoulder radius has been improved to provide an interior shape which sweeps entrained air out of the stopper opening

·         Glass stopper design uses a conical extension to displace excess sample which further insures no air entrapment in the sample

·         For reference see Method 5210-B: 5-Day B.O.D. Test (Standard Methods for Examination of Water and Wastewater)

·         Manufactured from 33 expansion, expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
