The HI-93754B-25 is a box of 25 reagent vials for COD, medium range *This method with chromium-sulphuric acid is officially recognised by EPA for wastewater analysis Each box of 25 vials is supplied with a Hanna certificate of quality.

The reagents are traceable to NIST SRM® 930 Hanna offers reagents to cover three separate ranges Three measurement ranges to satisfy every need - As COD levels vary depending on the application and process measuring points.

Simply choose the best range for the application: low range - 0 to 150 mg/L O2, medium range - 0 to 1500 mg/L O2 and high range: 0 to 15000 mg/L O2 Accurate and repeatable measurements ? Hanna COD reagents have been developed in accordance with Standard Methods 5220D, USEPA 410.4 and ISO 15705:2002 methods Pre-dosed vials ? Hanna vials contain approximately 3mL of pre-dosed reagent.

The operator just needs to add a small quantity of the sample Quick and accurate measurements ? With pre-dosed vials, test preparation time is dramatically reduced.

There is no time-consuming reagent preparation procedure or glassware cleaning Safe reagents ? Hanna COD reagents are safe for operators and the environment Vials and caps have been designed to avoid accidental reagent spills Due to the pre-dosed reagents, the amount of chemicals and handling time is minimised
