The vision of a human and innovative company

Driven by the spirit of enterprise and passionate about industrial creation, François Jalenques, a French physicist and entrepreneur, founded Interscience in 1979.

His ambition: create products of excellent quality, expand internationally and offer great services. First, he promoted the innovative Spiral method that automates the routine work of bacterial enumeration.

His model is also social. François Jalenques decides to set up his business in the heart of Cantal, cradle of his family origins, to revitalize industrial life in a deserted area.

A world reference

In 2012, brothers Emmanuel and Jules Jalenques took over the company by perpetuating this vision of a pleasant work environment, respectful of the ecology and the service of the people who work there.

The company currently employs 180 people in officies in France, Germany, USA, Singapore, China and Japan. We export 80% of our production through an energetic, multilingual sales team that coordinates a strong network of distributors in more than 130 countries.

The company has become a global reference as a manufacturer in the field of microbiology.
