Each box of 25 vials is supplied with a HANNA certificate of quality. The reagents are traceable to NIST SRM 930.

• Range:      0-150 mg/L
• Vial Cap Color:   Red
• Sample qty.:   2.0 mL

• Accurate and repeatable measurements

HANNA COD reagents have been developed in accordance with Standard Methods 520D, USEPA 410.4 and ISO15705:2002 methods.

• Pre-dosed vials

HANNA vial contains approx. 3 mL of pre-dosed reagent. The operator just needs to add a small quantity of the sample - 2 mL for LR and MR, and 0.2 mL for HR analysis.

• 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. Thanks to the pre-dosed reagents, the amount of chemicals is minimized.
