Basic Violet 10, universally known as Rhodamine B, is a highly fluorescent xanthene dye that produces an intensely brilliant, reddish-violet (magenta) colour. This liquid formulation is valued for its exceptional brightness and strong fluorescent properties, which are visible even at very low concentrations. It is a primary choice for manufacturing fluorescent printing inks and is widely used as a tracer dye in water flow studies due to its high visibility.
