The COD Test Tube produced by Aijiren is often used for chemical oxygen demand (COD) testing, and COD testing uses a specific oxidant to oxidize the substances (including organics) in the water sample. As the temperature and time decrease, the test requires This method is often widely used as a measure of organic pollutants.
The chemical oxygen demand test can better indicate the organic pollutants in industrial wastewater containing cyanide and heavy metals. COD testing can quickly respond to changing conditions before critical issues arise. With the Aijiren COD Test Tube, each user can easily perform highly sensitive and accurate water detection.
More than that, chemical oxygen demand is also an important test to evaluate the quality of wastewater and wastewater before discharge. Chemical oxygen demand (COD) testing can predict the oxygen demand of wastewater, which can be used to monitor and control emissions and evaluate the performance of treatment plants.
For the detailed steps of the chemical oxygen demand test, first add 2 mL of water or fresh water sample to a 16mm COD Test Tube containing digestion agent and catalyst. Cover the tube with a polypropylene lined polypropylene tube and heat it in a block digester at 150°C for 2 hours. The COD Test Tube produced by Aijiren is equipped with precise dose of reagents.
It is worth emphasizing that these COD Test Tube can only be used once and cannot be reused. Used COD Tubetests contain strong sulfuric acid and other chemicals, so reagents must be handled carefully. Chemicals in the pipeline should be disposed of in accordance with the requirements of local authorities. These test tubes have passed SGC certification.
