Aqueous Amido Black is a pre-mixed
Amido Black solution. It can be used to enhance or develop
blood-contaminated latent prints. Bloody latent prints, even those not
visible to the naked eye, may be developed on porous or nonporous surfaces,
such as cadavers, wood, or paper. Since this solution is aqueous (mixed with
water), it is a bit safer to use and you do not have to pre-soak the various
objects in Methanol as in the procedure for the mixed solution of the Amido
Black powder above. Shelf-life of Aqueous Amido Black: one year if not
subjected to extreme high or low temperatures. Do not refrigerate.
