Crime Scene Nile Red fluorescent dye is a specialized fluorescent dye engineered for microplastic research. This powerful analytical tool allows researchers to detect plastic particles in environmental samples by causing them to fluoresce under 460nm blue light. Important considerations before you order: 1) This chemical is made upon order and requires a several day delay before it ships. It cannot ship express by air. 2) Use directions are not included for this research material. 3) A 460nm UV light is not included. Packaged in a 250 mL amber bottle, this research-grade, methanol-based dye is protected from light degradation. To ensure the integrity of your research, each bottle is meticulously flushed with methanol to eliminate any potential plastic contaminants before filling. With its advanced detection capabilities, Crime Scene Nile Red is an essential component for environmental science laboratories and research facilities focused on microplastic analysis. Again: This chemical is made upon order and requires a several day delay before it ships. It cannot ship express by air.
