This low-cost, disposable cyanoacrylate fuming device is specifically designed for developing latent prints within five minutes, either in the laboratory or at a crime scene.
The innovative design of the Press & FumeTM allows first responders to process evidence for latent prints at a crime scene. Prints developed using cyanoacrylate (superglue) are considered strong and permanent; therefore, after photographs are taken, the evidence can be transported to the lab without damage to the developed prints.
Press & FumeTM consists of a 4″ L x 1.5″ W x .75″ H cardboard box with two prefilled, hermetically sealed glass ampoules containing cyanoacrylate and a high-density cotton pad saturated with a catalyst and accelerant solution, then thoroughly dried.
Using Press & FumeTM to develop prints is a simple, two-step procedure:
- Step 1 – After placing the Press & FumeTM box in the bottom of a fuming chamber or cardboard box, simply break the two ampoules with the ampoule breaker supplied in each case of kits.
- Step 2 – Cyanoacrylate vapors will immediately start fuming from the .125″ diameter vents on top of the Press & FumeTM box, and prints will fully develop within five minutes (in a 3 cubic ft. chamber).
Press & FumeTM can also be used for developing latent prints inside vehicles, using either two or four Press & FumeTM devices, depending on the size of the vehicle’s interior.
Prints developed with cyanoacrylate fuming will be very light gray or off-white. To enhance the contrast of cyanoacrylate prints on white or light-colored backgrounds, prints can be dusted using standard fingerprint powder; i.e. prints developed on a white coffee cup should be lightly dusted using black fingerprint powder. Prints developed on multicolored surfaces can be dusted with fluorescent powder.
Developing prints with Press & FumeTM is easier and faster than other fuming techniques and virtually eliminates the possibility of damaging developed prints when evidence is transported back to the lab.
