Series Automatic Fingerprint Fuming Cabinet (Export Model) - Application Introduction in Criminal Investigation Technology and Forensic Identification
The FPCE-502 Series Automatic Fingerprint Fuming Cabinet (Latent Trace Chemical Vapor Development System, export model with English operating system) is a core standardized equipment specialized for fingerprint development in criminal investigation technology and forensic identification laboratories. Based on the principle of ethyl cyanoacrylate (commonly known as 502 adhesive) vapor polymerization, it converts invisible latent sweat fingerprints on the surface of non-porous objects into clear, stable and extractable ridges through precise temperature and humidity control and automatic operation. It provides key physical evidence support for fingerprint identification and suspect identification. Its export model complies with international standards, balancing professionalism and versatility, and is an indispensable standardized equipment in the fingerprint development link of forensic identification.
The core performance of the equipment is accurately adapted to the needs of criminal investigation and forensic identification: automatic constant humidity control (75%-80% RH) ensures the consistency and repeatability of fingerprint development, meeting the rigorous requirements of forensic identification; integrated activated carbon waste gas purification ensures laboratory operation safety and personnel health, adapting to standardized identification processes; switchable Chinese/English operation interface (English system as standard for export model), combined with program-controlled operation, reduces human error and improves the success rate of fingerprint development and the integrity of ridges; the 700-liter large-capacity chamber can adapt to various involved non-porous objects, meeting the needs of simultaneous processing of multiple batches of physical evidence.
Combined with criminal investigation practice and forensic identification cases, its application value is prominent: Case 1, in a burglary case, latent fingerprints were left on non-porous objects such as on-site glass doors and windows and metal jewelry boxes. After automatic fuming by this equipment, complete fingerprint ridges were clearly developed. Subsequent dyeing enhancement treatment was carried out to accurately extract comparable ridges, providing key physical evidence for suspect fingerprint comparison and identification in forensic identification. Case 2, in the physical evidence identification of drug-related cases, the latent fingerprints on the surfaces of involved plastic packaging bags and glass containers had poor development effect by the powder method. With the vapor fuming technology of this equipment, fingerprints were successfully developed. Combined with observation and enhancement by multi-band light source, complete ridge characteristics were fixed, providing technical support for case characterization and identification of the association of involved personnel.
In summary, this equipment is widely used in scenarios such as latent fingerprint development on non-porous objects in criminal cases, standardized fingerprint processing in forensic identification laboratories, and preprocessing of fingerprints on difficult objects. It can realize automatic and standardized fingerprint development, improve the quality of physical evidence extraction and identification efficiency, and ensure the scientificity and repeatability of identification results. Its export model is suitable for the needs of international forensic identification laboratories, and it is a professional and standardized fingerprint development equipment in the fields of criminal investigation technology and forensic identification.
