  • Sublimation containment apparatus and method for developing latent fingerprints
    Patent number: 7487739
    Abstract: An apparatus and method for developing latent fingerprints having a heat source with a removably mounted chamber and sublimation system wherein the sublimation system is in communication with a heat emitting end of the heat source and an internal space of the chamber. Upon activating the heat source, heat transforms a cyanoacrylate of the sublimation system into vapor within the internal space of the chamber.
