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 I-2002 Dissolved Oxygen Meter is designed for accurately and quickly measuring oxygen in water levels from 0 - 15.0 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

The K-7513 uses the Indigo Carmine Method for testing.  In an acidic solution, oxygen oxidizes the yellow-green colored leuco form of indigo carmine to form a highly colored blue dye. The resulting blue color is proportional to the dissolved oxygen concentration in the sample. The results are displayed on the monitor in ppm (mg/L) Oxygen present. K-7513 Vacu-vials are used with the I-2002 Dissolved Oxygen Meter which gives the digital readout of the ppm (mg/L) of oxygen.


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 2 minutes for color development. 6. Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
