The TR125 Thermoreactor is for chemical digestion of samples that require it, such as in the determination of COD, TOC, total phosphate and total nitrogen. The required temperatures and reaction times are pre-programmed, and easy to select by using the keypad. Users can pre-select reaction times of 30, 60 and 120 minutes or can set it to operate continuously. When digestion is complete, the reactor automatically turns off and will sounds an alarm. The Chemical Oxygen Demand (COD) test is widely used as a measure of organic cantamination by determing the quantity of oxygen required for oxidation of reduced species including organic matter, in a water sample using a specific oxidizing agent, temperature and time reduction. COD testing is more reliable and is preferred to BOD testing as test results are more reproducible and are ready in two hours (or less) rather than 5 days. In addition, COD testing is a better indicator of organic pollutants in industrial wastewater containing cyanides and heavy metals. COD testing affords rapid response to changing conditions before critical problems develop. The TR125 COD reactor is fitted with 25 holes for 16 mm diameter vials.
