For samples with a concentration of 0 to 150 mg/L, use the low range COD vials. For higher concentrations the high range COD vials (0-1500 mg/L) should be used. If the COD

COD vials are hot now. • Cap tubes tightly. Switch on the COD Digester and fix the temperature at 150º C and set the time at 2 hours. • Place the COD vials into a block digester at 150 C and heat for two hours. • The digester automatically switches off.

Pre-filled with COD reagents, these digestion vials come in both EPA-approved and 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

2021/5/5 · Low-range or high-range vials are then selected for the COD test depending on the projected results. If the results to be expected are not known, both ranges can be used. One vial is marked “blank” while 3-4 vials are marked with a pre-defined standard level. 2 vials are also identified to be used for a wastewater sample duplicate run.
