Ready-to-Use, prefilled ST-COD Tubes– Simplifies sampling and testing workflow. Mercury-Free Tube Tests – Environmentally friendly when chloride interference is absent. Suppression of Chloride interference up to 1000 mg/L in LR & MR methods and up to 10,000 mg/L in HR method. The Lovibond® COD Setups allow highly sensitive and precise water testing with minimum effort. They measure the ST-COD concentration by photometric detection employing a linear relationship between absorbance and concentration.After adding the sample to a Lovibond® COD tube test (LR, MR according to ISO 15705:2002), it is heated in the reactor for two hours at 150 °C and then analyzed in the photometer.The COD Setups comprise the photometer, 25 tube tests for each of the two lower measuring ranges, a reactor for sample digestion and a vial stand. Delivery Content MD50 photometer in a robust carrying case. 25 ready-to-use COD tubes for each of the LR and MR methods. RD125 thermoreactor for sample digestion. Vial stand for 10 vials.
