Adorama DFO Traditional Mixture, Pump Spray, 4 oz

The DFO is a Ninhydrin analogue which also responds to amino acids in prints and is used to develop latent prints on paper with better results than Ninhydrin processing alone. It offer the traditional formulation as well as the new non-flammable Novec HFE-7100 based formulation. A laser or forensic light source (green, 525nm) will cause latent prints developed with DFO to show fluorescence.
