Abstract
A fingerprint capture or processing apparatus incorporates a casing defining a sealable chamber, a first support in the chamber for holding a source of a chemical fingerprint fixative agent, a second support in the chamber for holding an article to be tested for fingerprints, a filtration system connected to the chamber for removing contaminants from air in the chamber, and an air circulation assembly operatively connected to the casing for circulating air from the chamber and through the filtration system. Preferably, the air circulation assembly is a closed system, ensuring that no contaminants will be spilled to the ambient atmosphere prior to complete cleansing of the air inside the casing. A humidity control device may be connected to the air circulation assembly for modifying a humidity level in the chamber to a predetermined relative humidity, thus optimizing effectiveness of the chemical fingerprint fixation agent.
