History
Moving into the 21st century as one of the world’s most dynamic scientific instrument manufacturers, Group JOUAN can count upon a long history of experience.
In 1919 when war had just ended in Europe, Constant JOUAN, researcher at the Pasteur Institute, decided to devote all of his time to the creation of new laboratory instruments and the JOUAN company was born.

His ingenuity and creativity ensured the rapid growth of the company. The first to adapt an electric motor to a centrifuge (until then manually operated), he opened new perspectives in research and diversified towards chemistry and biology.
