EPA-Approved Reagent Vials are designed for performing chemical oxygen demand (COD) analysis in 30-, 100- and 150-count packs. This test is widely applied in industrial wastewater treatment plants to determine waste loading and to evaluate efficiency of treatment processes. Vials are available in both standard EPA-approved chemistry for reporting and a mercury-free chemistry for more convenient disposal.
