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.

The K-1420B Ammonia Kit was designed to accurately measure the levels of Ammonia in water from 0-500 ppm and 0-10,000 ppm. K-1420B uses the Hydroxybenzyl Alcohol (HBA) Method. In the ammonia test method that employs the Hydroxybenzyl Alcohol chemistry, free ammonia reacts with hypochlorite to form monochloramine. Monochloramine reacts with HBA, in the presence of sodium nitroferricyanide, to form a green colored complex. This test method measures the sum of free ammonia and monochloramine. Results are expressed in ppm (mg/L) ammonia-nitrogen, NH3-N. The Hydroxybenzyl Alcohol Method offers sensitivity similar to the Nesslerization Method and there is no generation of mercury-containing waste.
|1. Fill the micro-test tube approximately halfway with the sample to be tested.
|2. Fill the diluter snapper cup to the -ml- mark with distilled water. Add 6 drops of Stabilizer solution, 6 drops of Catalyzer solution, and 6 drops of Activator solution.
|3. Cap the diluter and shake it to mix the contents.
|4. Holding the VACUette almost horizontally,
touch the tip to the contents of the micro-test
|5. Place the VACUette between the vertical tip
guides on the inside of the dilutor snapper
cup and snap the ampoule tip.
|6. To mix the ampoule, invert it several times,
allowing the bubble to travel from end to
|7. Dry the ampoule. Obtain a test result 5
minutes after snapping the tip
|8. To obtain results, place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
