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
  • Activator Solutions
  • Diluter snapper cup
  • Sample cup top
  • Micro test tube
  • Instruction Manual
 

Method

The K-4605C Formaldehyde Kit was designed to accurately measure the levels of Formaldehyde in water from 0-1200 ppm and 1200-12,000 ppm. K-4605C uses the Purpald Method. Purpald® is subject to fewer interferences than Schiff's reagent or chromotropic acid procedures. A purple-colored complex is formed when Purpald in alkaline solution reacts with formaldehyde. Results are expressed as ppm (mg/L) CH2O.

Shelf-life of the Purpald Reagent: five months. We recommend stocking quantities that will be used within four months.

 

1. Add 7 drops of A-4201 Activator Solution to the empty diluter snapper cup. Fill the cup to the -ml- mark with distilled water then add 5 drops of A-4202 Activator Solution. Cap the cup and shake it to mix the contents.  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. Pull the VACUette into a vertical position. 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 12 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 flat comparator. Place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
