300ml Biological Oxygen Demand Bottle (BOD)

Bottle for determining the Biological Oxygen Demand, BOD

The BOD bottle made of high quality glass that meets the specifications of type 1, Class A borosilicate glass, ASTM E-438. The stopper is solid glass.
The capacity of the bottle is 300 ml. Both the bottle and the cap are unnumbered.

It has a screen-printed white field for labelling. The neck of the container is bell-shaped to form a seal to prevent air ingress during incubation.
The BOD of a liquid is the amount of oxygen that microorganisms, especially bacteria (aerobic or facultative anaerobic: Pseudomonas, Escherichia, Acetobacter, Bacillius), fungi and plankton consume during the degradation of the organic substances contained in the sample. It is expressed in mg/l.

General properties of borosilicate glass 3.3
It's very good chemical resistance to water, salt solutions, acids, bases and organic solvents. It is only attacked by hydrofluoric acid and, at high temperatures, by strong bases and phosphoric acid.
Low coefficient of linear expansion.
Highly resistant to sudden temperature changes.
Cleaning by autoclaving.
