Why Choose CHEMetrics Titrets?

CHEMetrics Titrets self-filing reagent ampoules make it easy to perform quick, accurate titrations of water samples. The handheld titrettor that comes with the kit allows the user to easily and reliably control the flow of the solution being measured without the need to count drops or use burets or other equipment. This unique design allows you to perform a titration anywhere and achieve reliable results for a variety of substances.

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, Tritrets 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 with valve assemblies

     -1 25 mL Sample Cup

     -Titrettor

     -Instruction Manual

Method:

The K-7050 Nitrite Kit was designed to accurately measure the levels of Nitrite in water from 500-5000 ppm. K-7050 uses the Ceric Sulfate Titrimetric Method. Ceric sulfate is the titrant and ferroin is the endpoint indicator. The method is free from glycol interference in samples that contain up to 75% glycol, making it particularly applicable to systems that contain nitrite corrosion inhibitors. Results are expressed as ppm (mg/L) NaNO2.

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:

Note: Images used in the following table show a total hardness and colors may differ from the ones shown. Read written instructions to know what color changes to expect from your substance.

1. Fill the sample cup to the 25 mL mark with the sample to be tested. 2. Snap the tip of the ampoule at the black snap ring.
   
3. Lift the control bar and insert the Titret assembly into the Titrettor. 4. Hold the Titrettor with the sample pipe in the sample. Press the control bar firmly, but briefly, to pull in a small amount of sample. The contents will turn green.
   
5. Press the control bar again to draw another small amount of sample into the ampoule. 6. Rock the entire assembly to mix the contents of the ampoule. Watch for a color change from green through blue to orange.
   
7.  Repeat steps 5 and 6 until a permanent color change occurs. 8. When the color of the liquid in the ampoule changes to orange, remove the ampoule from the Titrettor. Hold the ampoule tip pointed upward and read the scale opposite the liquid level. Results are expressed in ppm (mg/Liter) sodium hydroxide (NaOH).
