Sirchie CNA110 Cyano-Bloc Cyanoacrylate Pre-Treatment Wipes (5 Pack)

Cyanoacrylate (CA) fuming has proven to be a fast, efficient, and effective method of developing latent fingerprints on non-porous surfaces, but the method is not without its drawbacks. CA fumes attach to the moisture content of latent prints and just about everything else confined within the fuming chamber including the glass or polycarbonate sides and top. After just a few fuming cycles, it’s virtually impossible to see into the chamber and the film left by the process defies removal. These pre-treated pads are specially formulated to protect new, unused fuming chambers constructed of polycarbonate material or glass. Simply wipe the pad across all interior surfaces, allow to dry and apply a second coat. Then wet the supplied dry towel with water and wipe the interior. Extend the life of your fuming chamber and keep evidence visible throughout the fuming process.
