The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater.

• Tubes compatible with most spectrophotometers and thermoreactors on the market, such as Hach and Beckman
  • All COD Kits require the use of a Digestor Block and the V-2000 Photometer, a COD Photometer, or a spectrophotometer capable of accepting a 16 mm round cell.  Instruments sold separately.
• An economical alternative to Hach COD vials. Equivalent to Hach vials in chemistry and fully compatible with Hach instrumentation.
• Pre-dosed vials minimize waste and reduce test preparation time.
• No time-consuming reagent prep procedure or glassware cleaning.
• Reagents developed under the official dichromate method.
• Vial diameter is 16 mm and contains 3 ml of pre-dosed reagent.
• The products using the USEPA-approved method contain mercuric sulfate in the reagent to eliminate chloride interferences. The more readily disposable mercury-free product line is applicable when chloride interference is not a concern.
