Remove the cap from a vial for the selected range. Hold the vial at an angle of 45 degrees. Use a clean pipet to add 2.00 mL of sample to the vial. For 250–15,000 mg/L vials: Use a TenSette Pipet to add 0.20 mL of sample to the vial. 2 Oxygen Demand

Since the chemical oxygen demand test is a test that requires strong corrosive reagents, Aijiren uses the most inert and stable glass to produce the COD Test Tube, which is produced by Aijiren. COD Test Tube meets customer requirements for oxygen demand testing.

Pre-filled with COD reagents, these digestion vials come in either EPA-approved or mercury-free versions for low-, standard-, and ultra-high-range analysis. Each lot is tested to ensure superior quality from the cap and vial to the chemical contents. Glass vials are 16 mm x 100 mm to work with your existing COD reactor and spectrophotometer.

Details of Chemical Oxygen Demand Test: 2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours. The orange Hexavalent chromium is reduced to a greenish trivalent chromium.

CHEMetrics - Chemical Oxygen Demand (COD) Photometric Testing System CHEMetrics offers two dichromate reactor digestion methods (USEPA-accepted and Mercury-free) for fast, easy, safe determinations of COD levels in waste water — at about 30% lower cost than competitor's vials!

Chemical oxygen demand (COD) is one of the most important parameters in effluent monitoring and treatment. The COD test is used to predict the requirement an effluent will have for oxygen and hence the effluent's likely impact on the aquatic life of the receiving water course. Camlab water COD can be measured in three ranges.
