Rhodamine B molecular structure
Rhodamine B is an organic compound and a fluorescent dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. As it fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers. Rhodamine dyes are used extensively in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA. It is also often mixed with herbicides to show where they have been used. It is also used as fishers' bait as the colour invites the fishes. Rhodamine B well soluble in water, solubility is ca. 50 g/l, while the solubility in 30% acetic acid solution is ca. 400 g/l. Chlorinated tap water decomposes Rhodamine B. The solution of Rhodamine B adsorbs to plastics and should be kept in glass. Maximum absorption wavelength is 542 nm.
