Designed for sampling and for incubation of aqueous samples for biochemical oxygen demand (B.O.D.) analysis. The flared mouth forms a water seal which prevents the drawing of air into the bottle during incubation. The bottle shoulder radius has been improved to provide an interior shape which sweeps entrained air out of the stopper opening. Stopper design uses a conical extension to displace excess sample which further insures no air entrapment in the sample. Bottles and stoppers are correspondingly numbered. Capacity 300 mL. Overall dimensions:69 mm diameter, 165 mm height. Cases of 24. (K15070)
