The Sirchie Dark Small Particle Reagent (SPR) with Spray Head (500ml) 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 using standard lifting mediums.
