Description

DFO is a ninhydrin analog used to develop latent prints on porous surfaces. Its fluorescent properties make it especially useful on multicolored surfaces, where the background can interfere with subsequent photographs. DFO reacts with the amino acid content of fingerprint residue and does not interfere with subsequent analysis using ninhydrin, silver nitrate, or a physical developer. In fact, some laboratories report that using DFO improves the results obtained with ninhydrin.

According to the “Manual of Fingerprint Development Techniques” published by the Scientific Development Branch of the UK Home Office, DFO develops more fingerprints than ninhydrin. Tests conducted in the US indicate that DFO develops 2 1/2 times more than ninhydrin. Other tests indicate that DFO is also effective for developing latent blood prints. DFO may sometimes produce light-colored (pink) latent prints, but its good results are due to its fluorescent properties.

To view DFO fluorescence properly, you need to use ultraviolet light, such as BLUEMAXX™ or other alternate light sources.

DFO comes in a spray bottle containing 100ml of pre-mixed agent for better control and less waste.

DFO in crystal form is available for laboratories that prepare their own formulas. (Show description in original language)
Descripción

El DFO es un análogo de la nihidrina que se utiliza para revelar impresiones latentes sobre superficies porosas. Sus propiedades fluoro cromáticas lo hacen especialmente útil en superficies multicolores en las que el fondo puede estorbar en las fotografías posteriores. El DFO reacciona con el contenido de aminoácido del residuo de la impresión dactilar y no interfiere en el análisis posterior utilizando nihidrina, nitrato de plata o un revelador físico. De hecho, algunos laboratorios reportan que el uso de DFO mejora los resultados que se obtienen con nihidrina.

Según el “Manual de técnicas para revelar impresiones dactilares” publicado por la División de desarrollo científico policial del Ministerio del interior británico, el DFO revela más impresiones dactilares que la nihidrina. Pruebas realizadas en EE.UU. indican que el DFO revela 2 1/2 veces más que la nihidrina. Otras pruebas indican que el DFO también es eficaz para revelar impresiones latentes de sangre. En ocasiones, el DFO producirá impresiones latentes de color claro (rosado), pero los buenos resultados que ofrece radican  en sus propiedades fluorescentes.

La fluorescencia del DFO necesita para su correcta visulaización de la utilización de una  luz ultravioleta, tipo BLUEMAXX™ u otras fuentes de luz alternas.

El DFO viene envasado en un rociador  que contiene 100ml de  agente pre-mezclado para ofrecer mejor control y menos desperdicio.

El DFO en forma de cristal está disponible para aquellos laboratorios que preparan sus propias fórmulas.
