Risk Reactor Inc's DFTB-33PK100 UV Orange products are specially formulated versions of fluorescent dye for convenient use in water tracing and leak detection studies. This fluorescent orange dye is certified by International to ANSI/Standard 60 for use in drinking water. It may be detected visually, by ultraviolet light and by appropriate fluoremetric equipment. Today it is most often used visually. Visually the dye appears orange to red-orange, depending on its concentration and under ultraviolet light as bright yellow.

Dilution rate: one tablet per 60 gallons of water equals 1 ppm concentration in clear water Dissolves in one to three minutes.

Benefits of Risk Reactor Inc's IFWB-33 UV Orange Water Based Tracer:

High strength formulations for medium to large scale visual and fluorometric studies!
Most appropriate fluorescent products for quantitative analysis!
It is clear when diluted preventing stains and other unwanted marks!
Can be detected using one of our (portable battery operated ones available) black lights at significantly lower levels such as in the range of 10 ppb in ideal conditions!
Fluoresces under long wave black light!
Cleans up with water!
Highly concentrated saving you money!
Safe and non-toxic!
Can be used with our 6" Hand Held Black Light for mobility!
Can be used with UV sensors for automation!
Because of the fluorescent nature, IFWB-33 offers greater contrast than non-fluorescent tracers!

How to Use:
How Fluorescent Dye Tracing Products Work: The "visual" aspect of our dye products refers to normal reflection of light as color. The "fluorescent" aspect refers to special properties of some chemicals to absorb certain wavelengths and then emit, rather than reflect, light in response. The emission can be seen by using a "black" ultraviolet light or precisely measure Yellow Green with a fluorometer. The reflected and emitted light have different wavelengths and are, therefore, not the same color.

Fluorescent Properties are of Greatest Value When :
- Tracing must be done when there is no sun or sufficient artificial light (in a sewer or a cave, for instance).
- Precise quantified data is required.
- Very small amounts of tracing material is allowed.  

For Stream Tracing and Pollution Detection: Introduce tracers into the water at the source or suspected source of pollution. Allow sufficient time as calculated, to permit the dye tracer to reach the effluent or recipient location. Take samples of water for analysis.

Light Stability: Yellow Green is recommended for yellow and green backgrounds such as algae rich water. Yellow Green, blue, and yellow green should be used in water bearing heavy sediment loads or when passing through soil with high clay content. Industrial Yellow Green will absorb onto either. Photo degradation takes place in sunlight at different rates for different dyes. Yellow Green takes from approximately five to seven days and yellow green fades in two to three days. Blue, on the other hand, breaks down in three to four weeks. The color of all dyes will disappear if the solution is mixed with chlorine. Add approximately 4 grams of 12% bleach to every gram of product in solution.
