Lovibond COD Vial Test LR 3-150mg/l

Lovibond COD Vial Test LR 3-150mg/l is a pre-dosed, sealed tube reagent for photometric determination of Chemical Oxygen Demand (COD) in water and wastewater. The test uses the dichromate/H2SO4 method and is intended for municipal wastewater, industrial/process control and environmental water testing; tubes are heated for digestion and then analyzed in compatible colorimeters or test kits. The product is available in low-range (LR) vials covering 3–150 mg/L and includes mercury-free formulations where specified.
