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

     -low and high-range comparators 

     -1 25 mL Sample Cup

     -Neutralizer Solution

     -Activator Solution

     -1 mL syringe

The K-3810 Cyanide Kit was designed to accurately measure the levels of Cyanide in water from 0-0.1 and 0.1-1.0 ppm. K-3810 uses the Isonicotinic-Barbituric Acid Method. In the Cyanide CHEMets® and Vacu-vials® Kit, chlorine is added to a sample that has been buffered to pH 6. The resulting cyanogen chloride reacts with isonicotinic and barbituric acids to form a blue color. Results are expressed as ppm (mg/L) CN. 

Cyanide is used in many chemical and refining processes. It is found in effluent from electroplating and metal cleaning operations, coke ovens, steel manufacturing facilities, and gas scrubbers. Although cyanide can be safely removed by alkaline chlorination, its acute toxicity to aquatic life necessitates routine monitoring of effluents. The Maximum Contaminant Level for free cyanide in drinking water is 0.2 mg/L.

CHEMetrics' cyanide test kits are applicable to the monitoring of effluents and surface water supplies. It is recommended, however, that the sample be distilled and hydrogen sulfide be removed prior to analysis. 


1. Fill the sample cup to the 10 mL mark with the sample to be tested. Using the syringe, add 1.0 mL Neutralizer and stir. Shake the activator solution then add 5 drops and stir. 2. Place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip and the ampoule will automatically fill.
3. To mix the ampoule, tilt it from side to side, allowing the bubble to travel from end to end. 4. Dry the ampoule and wait 15 minutes for color development.
5. 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. 6. 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.
