The vapors in the portable vapor tank fume an object suspected of containing latent fingerprints. The portable vapor tank includes a shroud which encloses the vapors from the mist of atomized particles of cyanoacrylate ester, a first supporting member which supports the shroud and a second supporting member which supports the object in front of the spray container. The portable vapor tank also includes a timer which determines the duration of fuming with the vapors and purging apparatus which purges the vapors from the portable vapor tank.
