16mm chemical oxygen demand vials medium range for measuring water quality

Hanna Instruments offers a variety of instrumentation for measuring Chemical Oxygen Demand (COD). From benchtop meters and Photometers to certified reagents, Hanna has an accurate, affordable solution for nearly any COD application. Choose a category

Hanna Instruments offers a mercury-free or “green” method. These reagents are more sensitive to chloride interference, as mercuric sulfate is not present. The mercury-free COD reagents are available in a 0 - 150 ppm low range and 0 - 1500 ppm medium range.

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.

Pre-prepared low-range (3 - 150 ppm) or high-range (20 - 1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown.

Chemical oxygen demand does not differentiate between biologically available and inert organic matter, and it is a measure of the total quantity of oxygen required to oxidize all organic material into carbon dioxide and water.

Comprises of COD photometer, 25 tube tests covering lower measuring ranges, a reactor block for sample digestion and a tube stand. Waterproof acc. to IP 68, 1 hour at 0.1 meter. Scope of supply: Instrument in carrying case, 4 batteries (AA), adapter for round vials diam. 16 mm, 2 sets of tube tests 0-150 mg/l and 0-1500 mg/l, thermoreactor RD126, tube stand, 2 syringes, instruction manual.

Chemical oxygen demand can be used to estimate biochemical oxygen demand (BOD≈ ½ COD) and determine the dilutions needed for the BOD five-day test. Total COD is run on undiluted samples.

The V-2000 Photometer is a field-portable instrument that automatically tests pre-programmed analytes employing both CHEMetrics Vacu-vials® ampoules and Chemical Oxygen Demand ( COD) vials. It is best suited for those who want to test COD in addition to other analytes. Clear LCD display and simple menus.
