Certificate of Analysis and SDS.
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. Simply add 2 mL of your sample, heat in your digestor, and read in your spectrometer.
Although mercury-free vials are not approved for EPA Methods, they may be used for non-EPA COD testing when chlorine interferrence is not a factor. Ultra-high-range reagent vials have also not approved for EPA testing methods. COD digestion vials may contain acid, mercury, and silver and must be disposed of properly.
