Small Particle Reagent Kit

Small Particle Reagent (SPR) is an amazing solution. For light - colored surfaces, it's a suspension of fine molybdenum disulfide particles, while for dark - colored surfaces, it comes as a white suspension. It quickly adheres to the fatty parts of latent fingerprints, forming a gray or white deposit depending on the reagent used. This is a super - quick and easy latent print development process, even recommended by the U.K. Home Office, Scientific Research and Development Branch. Each kit comes with full instructions.

How to use: First, select the right type of Small Particle Reagent according to the surface color. Apply the reagent evenly on the surface where you suspect latent fingerprints. Let it sit for a short while until it adheres to the fingerprints. Then, gently wash off the excess reagent. Notice: Keep the reagent away from children and pets. Avoid contact with eyes and skin. If accidental contact occurs, rinse thoroughly with water. Maintenance: Store the kit in a cool, dry place. Make sure the container is tightly closed after use to prevent the reagent from drying out or getting contaminated.
