Why Choose CHEMetrics Vacuettes kits?

VACUettes ampoules are designed for highly concentrated samples. They employ a patented auto-dilution feature that eliminates the need for a time-consuming and error-prone preliminary dilution. As a result, the entire test takes only 2 to 3 minutes, with a rate of accuracy comparable to a volumetric procedure. The basic design of these 7 mm ampoules is the same as CHEMets ampoules, however, a capillary tip is attached to the tip of each ampoule.

Safe and Reliable Results:

While traditional methods often require multiple steps and thorough preparation, these test kits allow you to obtain dependable results with a few simple steps. By simplifying the testing method, Vacuettes test kits reduce the potential for operator error. Additionally, each of the ampoules contained in the test kits is vacuum sealed which helps eliminate the problem of obtaining inaccurate results from stale or unstable reagents. These reagents are stored right in the tip of each ampoule and sealed in glass, thereby minimizing direct contact with the chemicals.

What's Included:

     -30 self-filling Ampoules

     -Comparator 

     -Diluter snapper cup

     -Reaction tube with lid

     -1.0 mL syringe

     -Instruction Manual

 

Method:

The K-6909D Nitrate Kit was designed to accurately measure the levels of Nitrate in water from 0-45 ppm. K-6909D uses the Cadmium Reduction Method. Nitrate is reduced to nitrite using cadmium as the reducing agent. The resulting nitrite concentration is then determined colorimetrically. This method is applicable to drinking and surface waters, as well as domestic and industrial wastes. Nitrite will interfere with this test. Results are expressed as ppm (mg/L) NO3-N or NO3

Nitrate is the most completely oxidized form of nitrogen. It is formed during the final stages of biological decomposition, either in wastewater treatment facilities or in natural water supplies. Low-level nitrate concentrations may be present in natural waters. However, a Maximum Contaminant Level of 10 ppm nitrate-nitrogen has been established for drinking water by the USEPA. 

Shelf-life: The refill and color comparator contained in this kit have shelf-lives of 12 months

1. Using the 1.0 mL syringe obtain 1.5 mL of the sample to be tested and dispense it into the empty reaction tube. Dilute the contents of the reaction tube to the 15 mL mark with distilled water. 2. Empty the contents of 1 Cadmium Foil Pack into the reaction tube. Cap the reaction tube and shake it vigorously for exactly 3 minutes. Allow the sample to sit undisturbed for 2 minutes.
3. Pour 10 mL of the treated sample into the 25 mL sample cup. Do not transfer cadmium particles into the sample cup. 4. Place the VACUette between the vertical tip
guides on the inside of the dilutor snapper
cup and snap the ampoule tip. 
 
5. To mix the ampoule, invert it several times,
allowing the bubble to travel from end to end. Dry the ampoule and wait 10 minutes for color development.
6. To obtain results place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
