COD Reagent Vial: High Range COD Test Vials - 20 to 1500 mg/L - 150 Tests

High Range COD Digestion Vials for Wastewater COD Testing

Mixing your own dichromate reagent for COD is slow, hazardous and hard to keep consistent. Hach High Range COD Digestion Vials come pre-filled and ready for the Reactor Digestion method, so the analyst only adds sample, digests and reads.

The High Range COD Digestion Vials cover 20 to 1500 mg/L COD and are USEPA approved for wastewater analysis using Hach Method 8000. Each pack holds 150 vials for busy effluent treatment plant laboratories.

Key Benefits

Efficiency

Pre-measured reagents cut preparation time to adding sample and capping. The High Range COD Digestion Vials go straight into a COD reactor for digestion. Details are on the Hach COD vials product page.

Accuracy

Factory-filled vials give the same reagent volume every time, which keeps results repeatable between analysts and shifts. Read the vials on a photometer such as our portable visible spectrophotometer.

Safety and comfort

Sealed glass vials keep concentrated sulfuric acid and dichromate away from the analyst, so handling of High Range COD Digestion Vials is safer than open reflux.

Key Features

• USEPA approved Method 8000 for wastewater
• 20 - 1500 mg/L range for industrial effluent
• Pack of 150 for high-throughput labs
• Works with most Hach photometers

Solving Common Lab Problems

Effluent COD above 150 mg/L? The High Range COD Digestion Vials read up to 1500 mg/L without extra dilution steps.

Inconsistent hand-made reagent? Pre-filled vials remove mixing errors.

Need a reportable method? Hach High Range COD Digestion Vials follow USEPA approved Method 8000.
