Sirchie DFO Pump Spray, 100ml, 3.38oz

If you're in search of an effective solution for developing latent prints on porous surfaces, the DFO Pump Spray is your go-to product. This high-quality ninhydrin analog is specifically designed to work seamlessly on multicolored surfaces, where background interference could potentially disrupt subsequent photography.

The DFO Pump Spray's fluorochrome properties react with the amino acid content of fingerprint residue, ensuring it doesn't interfere with further analysis using ninhydrin, silver nitrate, or physical developer. In fact, it's been reported by some labs that the use of DFO enhances the results obtained with ninhydrin.

Citing the "Manual of Fingerprint Development Techniques" by the Police Scientific Development Branch of the British Home Office, DFO is proven to develop more fingerprints than ninhydrin. Tests conducted in the U.S. reveal that DFO can develop up to 2-1/2 times as many prints as ninhydrin.

This versatile product is also effective in developing latent blood prints. While DFO occasionally produces lightly colored (pink) latent prints, its real strength lies in its fluorescent properties. DFO fluorescence can be produced using ultraviolet light, BLUEMAXX, and other alternative light sources.

The DFO Pump Spray is conveniently packaged in a durable pump spray bottle containing 100ml of pre-mixed reagent, ensuring better control and less waste. For labs preparing their own formulations, DFO is also available in crystal form.

Whether you're a professional photographer or a forensic expert, the DFO Pump Spray is an essential tool for your work, offering unparalleled effectiveness and reliability.
