About us

ATTO-TEC GmbH is a fully privately owned company which develops and markets fluorescent labels and dyes. The 15-employee company located in Siegen in Southern NRW, was founded in 1999 as a spin-off of the University of Siegen. It is staffed by internationally renowned scientists with long-time expertise in fluorescent dye chemistry. Fluorescent applications now have become so diversified and sophisticated that there is an ever growing demand for new and better fluorescent dyes. Consequently to take up the challenge ATTO-TEC has developed several new dyes which nowadays are used with great success by scientists throughout the world. Researchers prefer ATTO-labels for their high purity and excellent performance. In many applications ATTO-dyes are not merely an alternative, they are the better choice. Besides its catalogue portfolio, ATTO-TEC also offers to develop customized dyes based on own patents in order to protect its know-how.
