10mL chemical oxygen demand vials with high range for lab use

The glass performs excellent at high temperatures and is chemical resistant to acidic, neutral and alkali solutions. All our vials are packed in a clean environment to ensure you receive contaminant free product every time. Volume: 2 mL Size: 12 x 32 mm I. D. : 10 mm .

1/6/2016 · A chemical oxygen demand (COD) test is used to measure the amount of organic compounds in a water sample. It measures the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrate. The most common method uses COD vials with overall results being achieved

For determination of Chemical Oxygen Demand (COD) by the Reactor Digestion Method, using TNTplus™ vials. Hach Method 8000. Range: 20-1500 mg/L COD. Pack of 25 tests TNTplus COD High Range (20-1500 mg/L) vial tests with automatic method detection No Reagent Blank Necessary Innovative Vial.

The HI93754C-25 are reagent vials that follow the dichromate method for the high range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each box for traceability.

Chemical oxygen demand (COD) is used as a measure of oxygen requirement of a sample that is susceptible to oxidation by strong chemical oxidant. The dichromate reflux method is preferred over procedures using other oxidants (eg potassium permanganate) because of its superior oxidizing ability, applicability to a wide variety of samples and ease of manipulation.

If using High Range Plus COD Digestion Reagent Vials, multiply the result by 10. For most accurate results with samples near 1500 or 15,000 mg/L COD, repeat the analysis with a diluted sample.

5. The sample vials was inserted into 16-mm. 6. READ the results in mg/L COD. 7. If High Range Plus COD Digestion Vials was used, the result was multiplied by 10. The most accurate results was samples near 1500 or 15000 mg/L COD, the analysis was repeated with diluted sample.

•The Biochemical Oxygen Demand is an empirical test that measures the amount of oxygen used by bacteria as they metabolize organic matter at 20 oCelsius, in the dark, usually over a 5 day period. •(pH 6.5 to 7.5 is best) •Two types of bacterial activity:

Hach's USEPA-approved dichromate COD Method is the most widely used chemical oxygen demand (COD) method for NPDES reporting in the world. COD Digestion Vials, High Range, pk/150 | Hach USA - Parameter/Reagent

The HI94754B-25 are barcode reagent vials that follow the EPA approved method for the medium range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each box for traceability. Pre-dosed reagents for ease of use

These 8mm vials have a 8-425 thread finish. They are manufactured from high-quality glass and fit a variety of autosamplers. Store your samples in these vials to eliminate leaching of ions while maintaining a consistent pH for the life of your sample. Storage vials range from 2mL to 40mL.
