The Sirchie REDescent Fluorescent Latent Fingerprint Powder is a fluorescent red oxide powder for developing latent (non-visible) prints on nonporous surfaces such as painted wood, metal, and most plastics. The fluorescent red color of the powder provides visibility on dark and multicolored surfaces, and displays enhanced print details when viewed with ultraviolet light. An ultraviolet light source (sold separately) with light in the ultraviolet or blue parts of the spectrum (254 to 525nm) can be used to excite the fluorescence. The powder adheres to oily or moist deposits, particularly sebaceous secretions that may contaminate the fingertips. It produces optimal results on newer prints found on dry, smooth, non-adhesive surfaces. Excess powder can be removed using a duster (sold separately). The jar contains a 2oz. (59mL) volume of powder. Fingerprint powders are used in forensic investigations and classroom demonstrations to develop and collect fingerprint evidence.
Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.
Sirchie manufactures criminal investigation and forensic science products. The company, founded in 1927, is headquartered in Youngsville, NC.
