EasyPREP COD-200

Automated Chemical Oxygen Demand (COD) Analyzer

This all-in-one, unattended, COD system automates the mixing, heating, cooling, and analysis of COD samples.

COD tubes are placed in a digestion block for sample digestion, followed by shaking and cooling. They are then transferred to the spectrophotometer where samples are analyzed. Results and calculations are displayed in real-time.


The COD-200 offers turbidity detection. In turbid samples, light scattered from solid particles may interfere with the sample’s measured absorbance. In COD analysis, the presence of turbidity can cause deviations of up to 30% from the real sample value. This capability allows the end user to confidently analyze samples knowing that the turbidity level is adequate for COD analysis.
