HI-93754F-25 Low Range COD reagents
HI-93754F-25
Hanna HI-93754F-25 COD reagent vials are designed specifically to comply with ISO 15705 requirements. Our reagent range starts from 0, providing full coverage for testing within the low range required by specific industrial processes and water and wastewater applications. Our low range chemical oxygen demand reagents are available in boxes of 25 vials, with each box containing a Certificate of Analysis - providing peace of mind for accurate, compliant testing.
The Hanna COD reagents range covers everything from low to ultra high, with specialised solutions to suit different requirements. All reagents are stocked in the UK for prompt delivery and are fully compatible with the Hanna Iris Spectrophotometer and our advanced photometers range.
The HI-93754F-25 is a box of 25 reagent vials for COD, low range ISO
*This method method follows the official method ISO 15705
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.
About the testing methods
- Dichromate EPA - Method with chromium-sulphuric acid is officially recognised by EPA for wastewater analysis.
- Dichromate mercury-free - This method is recommended for general purpose analysis with no chloride interference.
- Dichromate ISO - Method follows the official method ISO 15705. COD MR ISO method is 0 – 1000 mg/L. Meter can read higher.
