15mL chemical oxygen demand vials with low range on stock

CBOD or Carbonaceous BOD represents the Biological Oxygen Demand (BOD) from organic compounds and oxidation of inorganic compounds such as ferrous iron and sulfide. Any BOD from nitrifying organisms, which consume oxygen in the nitrification process of converting ammonia to nitrate, is removed by adding a nitrification inhibitor.
