Why Choose Vacu-vials?

CHEMetrics Vacu-vials self-filling ampoules are a great way to test for dissolved substances in liquid. Unlike our visual test kits, the Vacu-vials test kit allows you to obtain an instrumental result using the CHEMetrics Direct-Redout Photometers or any spectrophotometer capable of accepting a 13m diameter round cell. When using equipment from another manufacturer, set the spectrophotometer to absorbance mode, select the wavelength specified by the Vacu-vials kit instructions, and follow the test procedure. The K-7003 Nitrite Kit was designed to accurately measure the levels of nitrite in water from 0-1.00 ppm.ppm. 

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, Vacuvials 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

     -25 mL Sample Cup

     -Ampoule blank

     -Instruction Manual

Method:

The K-7003 uses the Azo Dye Formation Method. With the Azo Dye Formation method, Nitrite diazotizes with a primary aromatic amine in an acidic solution to produce a highly colored azo dye. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Nitrate will not interfere. Results are expressed as ppm (mg/L) NO2-N. 

Nitrite, an intermediate in the nitrogen cycle, is formed during the decomposition of organic matter but readily oxidizes to form nitrate. These processes occur in wastewater treatment plants, water distribution systems, and natural waters. Nitrites are useful as corrosion inhibitors, preservatives, pigments, and in manufacturing many organic preservative chemicals. A Maximum Contaminant Level of 1 mg/L has been established by the USEPA for nitrite-nitrogen in drinking water.

 

How to Use:

1. Fill the sample cup to the 25 mL mark with the sample to be tested. 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
5. Wait 10 minutes for color development. 6. Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
