Why Choose CHEMetrics Chemets kits?

CHEMetrics Chemets self-filing reagent ampoules are a great way to test for dissolved substances in liquids. These visual test kits allow you to obtain results by measuring the color of the sample according to the color comparators provided with the kit. This unique method allows you to attain results quickly and accurately with minimal contact with potentially hazardous materials.

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, Chemets 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


     -1 25 mL Sample Cup

     -Stabilizer Solution

     -Catalyzer Solution

     -Activator Solution

     -3 mL syringe

     -Instruction Manual



The K-1420 CHEMets Visual Kit is a visual indicator kit for measuring ammonia in water levels from 0-4 and 0-80 ppm.  This device uses the Hydroxybenzyl Alcohol (HBA) Method for testing. 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 sample cup to the 25 mL mark with the sample to be tested. 2. Add 4 drops of Stabilizer Solution, then 4 drops of Catalyzer solution, then 4 drops of activator solution. 
3. Immediately place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip and the ampoule will automatically fill. 4. To mix the ampoule, tilt it from side to side, allowing the bubble to travel from end to end.
5. Dry the ampoule. Obtains results 8 minutes after snapping the top. 6. To obtain results, place the ampoule between the color standards, moving it along the comparator until you can determine the closest match.
