Chemical Oxygen Demand. Chemical Oxygen Demand (COD) is a measure of the biologically available and inert organic matter that is susceptible to oxidation by a strong oxidizing agent. The Hanna COD method is based on the well-established closed dichromate-reflux colorimetric method. The colorimetric measurement of COD is faster and easier to

The Sample Cell Vial produced by Aijiren is often used for water quality testing. Its small size and flat design allow it to stand stably on a table or cabinet. Compared with the 16mm COD Test Tube, which is also used for water quality monitoring, it capacity is larger. 25*60mm 20ml Sample Cell Glass Vial.
