COD vials are hot now. • Cap tubes tightly. Switch on the COD Digester and fix the temperature at 150º C and set the time at 2 hours. • Place the COD vials into a block digester at 150 C and heat for two hours. • The digester automatically switches off. Then

Chemical Oxygen Demand (COD) Chemical Oxygen Demand (COD) is the amount of oxygen required for the chemical oxidation of the organic matter by the strong oxidizing agent under the acidic condition, it is a measure of oxygen required to oxidize water-soluble and micro-organic materials. Also, it provides an index to assess the effect that the
