Glassco BOD Bottle 300mL

A Glassco BOD Bottle (Biochemical Oxygen Demand) with a capacity of 300 milliliters is another size variant of laboratory glassware used for conducting BOD tests. Like other BOD bottles, it serves the purpose of holding water samples under controlled conditions to measure the biochemical oxygen demand.

In a BOD test, the bottle is typically filled with a water sample, and then sealed to create an airtight environment. This allows the dissolved oxygen level in the water to be measured at the beginning and end of a specified incubation period, usually 5 days at 20°C. The difference in dissolved oxygen concentrations before and after incubation provides insight into the amount of oxygen consumed by microorganisms during the degradation of organic matter in the sample.

The 300ml capacity of the Glassco BOD bottle refers to the volume of liquid it can hold. These bottles usually feature a narrow neck and are designed to be stopped to maintain a sealed environment during the incubation period. Made of clear glass, they enable easy observation of the sample during testing. They are commonly utilized in environmental and water quality laboratories for assessing the levels of organic pollution in water bodies. Click to Learn More
