Fluorescent dyes and stains

Fluorescent dyes are used in leak detection, water tracing, highlighters and safety colours, security printing, textile and plastic colouring, and laboratory science. Stains help pathologists, microbiologists and biologists see cells and tissues under the microscope. Some dyes serve both industrial and laboratory markets, but in different grades, and the laboratory grades carry a tested dye content and a batch-specific performance check.

For laboratory use, ask for biological stain or certified grades with dye content and performance testing, plus absorbance and emission maxima. For industrial use, specify strength, shade, solubility and form. Some stains are toxic or classified as carcinogens, so check handling guidance. Fluorescent probes for research are listed in the laboratory reagents section as well.
