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
  • Comparators
  • Diluter snapper cup
  • Activator Solution
  • Micro test tube
  • Instruction Manual
 

Method

The K-7904D Peracetic Acid Kit was designed to accurately measure the levels of Peracetic Acid in water from 0-30 ppm and 0-150 ppm. K-7904D uses the DPD Method, in which the sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DPD (N, N-diethyl-p-phenylenediamine) to form a pink-colored species that is directly proportional to the peracetic acid concentration in the sample. Results are expressed as ppm (mg/L) peracetic acid. 

Various oxidizing agents such as halogens, ozone, and cupric ions will produce high test results. Hydrogen peroxide does not interfere if present at levels comparable to the peracetic acid levels.

 

1. Add 5 drops of Activator Solution to the empty snapper cup. 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 1 minute 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 flat comparator. Place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
