Used primarily on paper surfaces as an alternative to DFO, 1/2-Indanedione is a fluorescent latent print dye that is visualized at 520nm with filtration between 570-590nm, particularly for weak fingerprints. Its chemical purity is crucial to performance—ours is consistently >99% pure.

• Chemical purity typically >99.5% pure
• Secure-sealed vials with pre-measured quantities for the most common working solutions
• No measuring or weighing is necessary—just add the contents to your solution
