DFO 1.8 Diazafluoren 9 One, 100 ml
DFO is a ninhydrin analog used for developing latent prints on porous surfaces. Its fluorochrome properties make it especially useful on multicolored surfaces where the background would interfere with subsequent photography. DFO reacts with the amino acid content of fingerprint residue and it will not interfere with subsequent analysis using ninhydrin, silver nitrate or physical developer.
DFO in crystal form is available for those labs preparing their own formulations. Ether Based, 100 ml Dropper.
