Basic dyes are water-soluble cationic dyes, mainly used for the dyeing of acrylic fibers, also can be used to dye wool and silk. Acetic acid is usually added to the dye bath to help the dye uptake onto the fiber. Basic dyes are also used for paper coloring.

Fluorescent tracers are fluorescent dyes or molecules that emit light when exposed to ultraviolet (UV) or visible light. The fundamental characteristic includes their ability to absorb light at particular wavelengths and emit light at extended wavelengths. When photons are absorbed, fluorescent tracers excite electrons to a higher energy state before these electrons emit light during their return to the ground state. Through this property, researchers can visualize molecular processes in biological systems, materials and chemical environments with high sensitivity. Alfa Chemistry offers a comprehensive range of fluorescent tracers that serve both traditional and modern research applications in life sciences and analytical chemistry along with nanotechnology.

Fluorescent tracers are fluorescent dyes or molecules that emit light when exposed to ultraviolet (UV) or visible light. They are widely used in various industries and applications such as healthcare, food and beverages, oil and gas, environmental monitoring, biotechnology, etc.Based on their different properties or characteristics, Alfa Chemistry offers you three categories of fluorescent tracers
