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

     -Micro test tube

     -Instruction Manual

 

Method:

The K-7004D Nitrite Kit was designed to accurately measure the levels of Nitrite in water from 0-80 ppm. K-7004D uses the Azo Dye Formation Method, in which Nitrite diazotizes with a primary aromatic amine in an acidic solution to produce a highly colored azo dye. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Nitrate will not interfere. Results are expressed as ppm (mg/L) NO2-N. 

Nitrite, an intermediate in the nitrogen cycle, is formed during the decomposition of organic matter but readily oxidizes to form nitrate. These processes occur in wastewater treatment plants, water distribution systems, and natural waters. Nitrites are useful as corrosion inhibitors, preservatives, pigments, and in manufacturing many organic preservative chemicals. A Maximum Contaminant Level of 1 mg/L has been established by the USEPA for nitrite-nitrogen in drinking water.

 

1. Fill the diluter snapper cup to the -ml- mark with distilled water. 2. Fill the micro-test tube approximately halfway with the sample to be tested.
3. Holding the VACUette almost horizontally,
touch the tip to the contents of the micro-test
tube.
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.
6. Dry the ampoule. Obtain the test result 10 minutes after snapping the tip.
7. Place the ampoule into the center of the round comparator and hold it toward a source of light, viewing from the bottom. Rotate the comparator until the color below the ampoule shows the closest match. 8. For higher concentrations, use the flat comparator. Place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
