BOD Bottle with solid stopper 300 ml

A BOD (Biochemical Oxygen Demand) bottle with a solid stopper and a 300 ml capacity is laboratory glassware used for measuring the oxygen demand of organic substances in water samples. It is crucial for testing water quality and assessing pollution levels in environmental monitoring.

The solid stopper ensures an airtight seal, preventing atmospheric oxygen from entering the bottle, which is essential for accurate measurement of the oxygen consumed by microorganisms during incubation. The 300 ml size provides a larger volume than smaller BOD bottles, allowing for more sample analysis or replicates in water testing laboratories.
