COD (Chemical Oxygen Demand) digestion vial is a specialized laboratory glassware used for the determination of chemical oxygen demand in water samples. COD is a measure of the amount of oxygen required to chemically oxidize organic and inorganic substances present in water. COD digestion vial typically consists of a glass or plastic vial with a tight-fitting screw cap. The vial is designed to withstand high temperatures and chemical reactions that occur during the COD digestion process.
