Safariland DFO (1,8-Diazafluoren-9-One) Powder, 1g

The purity range (99%>99.5%) provides improved fluorescence, particularly for weak fingerprints. Research has shown that DFO (1g) develops two to three times more latent prints on paper items than the Ninhydrin process alone. Each vial is security-sealed and is packaged in ready-to-use quantities for the most common working solutions. No measuring or weighing is necessary - just add the contents to your solution. Indefinite shelf life when stored in a cool, dry place.
