  1. Small Particle Reagent - Black

    Small Particle Reagent - Black

    Small Particle Reagent (SPR) is quick, inexpensive and effective on fresh fingerprints. SPR is composed of finely ground particles suspended in a detergent solution. These particles adhere to the fatty constituents of latent fingerprints to form a visible deposit. Latent prints developed using this method may be lifted usin... Learn More

    SPR - Aerosol - Black or White

    SPR Black is an aerosol-based fingerprinting product for the development of latent prints on wet, light, smooth non-porous surfaces. Earlier methods based on dispersed particles in aqeuous solutions required the field mixing of powders, water and other ingredients to achieve similar results. The process was messy and cumber...

  4. Sudan Black

    Sudan Black

    The Sudan Black method of fingerprint development relies upon the presence of oils and other sebaceous materials present in latent prints. One of the best methods you can use on greasy or waxy nonporous surfaces such as glass, metal, milk cartons, interiors of gloves, and candles. The resulting print development is a dark b...

    Thermanin

    ThermaNin is a ninhydrin derivative for developing fingerprints on thermal paper. Regular ninhydrin and DFO solutions are either based on polar solvents (like acetone or ether) or contain them. These turn the top (active) layer of thermal paper gray or black. Research has found that hemiketals of ninhydrin are soluble in pe... Learn More
