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-2703 Chlorine Dioxide Kit is designed to accurately measure the levels of Chlorine Dioxide in water from 0-11.00 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

     -1 25 mL Sample Cup

     -Stabilizer Solutions

     -Ampoule Blank

     -Instruction Manual


The K-2703 uses the DPD method. Chlorine dioxide is used as an oxidizing microbiocide in industrial cooling water treatment, the dairy industry, the meat industry, and many other food and beverage industry applications. It is used as a bleaching agent in the pulp and paper industry, and as a disinfectant in municipal water treatment. Industrial waste treatment facilities use chlorine dioxide because of its selectivity for certain compounds, including phenols, sulfides, cyanides, thiosulfates, and mercaptans. The oil and gas industry uses chlorine dioxide for downhole applications and as a stimulation enhancement additive. The Maximum Residual Disinfectant Level for chlorine dioxide is 0.8 mg/L in drinking water.


How to Use:

1. Fill the sample cup to the 15 mL mark with the sample to be tested. 2. Add 4 drops of the Neutralizer Solution. Stir to mix the contents of the cup.
3. 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 and wait 2 minutes for color development. 6. Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
