Basic Yellow Latent Print Dye is a yellow-colored dye used to stain cyanoacrylate-developed prints. Using Basic Yellow helps to view and photograph latent prints on non-porous, multi-colored surfaces where it is typically difficult to view ridge detail of latent prints under normal lighting.

Basic Yellow is used in conjunction with cyanoacrylate to form a compound that will fluoresce under a forensic light source. Note: It should never be used on latent prints that have not been fumed with cyanoacrylate.

There are three different methods to use Basic Yellow. First, a user may submerge the item into a container of the liquid Basic Yellow. The second option for application is spraying the item with liquid Basic Yellow. The last method for applying Basic Yellow is brushing the liquid Basic Yellow onto the item using a soft bristle brush. (We suggest our camel hair brush, Reorder No. BR-C-1.5)

No matter which method is used, Basic Yellow should set for about one minute and then be rinsed before viewing the developed print. To view the print, use a forensic light source in a dark room. Basic Yellow fluoresces well between 365 and 485 nanometers. At this point, the print should be photographed and kept as evidence.

Note: Though not usual, our dyes and stains, depending on the quantity ordered, may require an additional hazardous shipping charge be added. We will contact you if this is the case.
