DFO 1,8-Diazafluoren-9-One, 5g

11-2793
99% Pure! This purity range (99% > 99.5%) provides improved fluorescence, particularly for weak fingerprints. Research has shown that DFO develops two to three times more latent prints on paper items than the Ninhydrin alone. DFO is responsive to amino acids present in body proteins. If used in sequence with Ninhydrin, use DFO first. Each vial is security-sealed. DFO powder has an indefinite shelf life as long as it is stored in a dry, cool place. Requires an additional surcharge to ship by air. Size: 5g
