BOD Bottle or an incubation bottle is a main apparatus used for the Biological Oxygen Demand (BOD) test. During the 5-day BOD (BOD5) or 7-day BOD (BOD7) test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature.
General
The bottle is normally designed to have a special shoulder radius to push out all air from the inside of the bottle when a sample solution is being filled into the bottle. The BOD bottle usually has a ground-glass stopper, although plastic stoppers are sometimes used and a flared mouth which form a water seal preventing the air from the outside of the bottle coming in. BOD bottles are made of borosilicate glass, which can be either clear or amber.
This type of bottle uses two kinds of stopper: the glass pennyhead and the glass robotic stopper.
BOD bottles come in sizes between 60 and 300 ml.
Availability
BOD bottles are sold by lab suppliers.
