However, time is a factor that cannot be ignored and therefore this method is presented to minimize the time element between the introduction of the Super Glue in the fuming chamber and the actual development of the latent prints. Fuming is increased in a shortened period of time through the ...
Problem:Difficult to clean interior. Conventional chambers are made of glass, plastic or painted steel which can be hard to clean. Users spend more time cleaning with their heads in the chamber, which exposes them longer to noxious vapors and solvent based cleaners. Solution:The durable stainless...
A study on the optimal conditions for latent fingerprint development using cyanoacrylate fuming method in vacuum chamber Cyanoacrylate fuming mehod is effective for latent fingerprints developing on non-porous surfaces. In this study, we investigated optimal conditions for la... JS Yu,JS Jung,S Lim...
within the fuming chamber. Fuming by this method is typically accomplished by evacuating the chamber down to twenty-five inches of mercury and allowing the items to fume under vacuum for about twenty minutes. Thereafter, the latent prints are "locked on" the item for future print removal and ...
Sufficient humidity in the chamber during fuming is the critical element of the process that fixes the developed prints. If the humidity is too low, the fumes will form a visible residue as expected, but it will be ashy in texture and will wipe away from the evidence surface, taking with ...
No ducting is required for this fuming chamber. Since prints may be easily developed at the scene, irrelevant evidence may be ruled out, thus saving valuable laboratory processing time and storage space.These fuming enclosures quickly fix latent fingerprints at the crime scene, while protecting the...
Patent-pending, collapsible design allows components to nest together into a compact package with handle Clear, shatter-resistant polycarbonate chamber provides visibility to the evidence during the fuming process Microprocessor-controlled heater allows the user to set the temperature in one degree increment...
clear protective fuming chamber to contain the fumes as they react with the latent prints; an exhaust blower; and particulate/carbon exhaust filter. No ducting is required for this fuming chamber. Since prints may be easily developed at the scene, irrelevant evidence may be ruled out, thus savi...
