Our products
Our products are used in microbiological analyses labs to test any sample enabling the research of contaminants and pathogens. They are largely used in the agrofood industry to check if the products are safe for consumption and in the pharmaceutical, cosmetic, clinical and veterinary industries to test the efficiency of creams and medecines for example. They also equip labs in hospitals, universities, research centers, private and public labs.

We have built a solid reputation of a company with innovative products meeting success because they are adapted to the user’s needs. Since the beginning we have had a passion for research and development and looking for profit has never been the main goal. We are also proud to provide our teams with the best work environment and have designed an ecological surrounding for our research center and factory.

How it all started
The company was founded in 1979 by François Jalenques, a physicist fond of entrepreneurship. He started by promoting an innovative plating method for the research of contaminants and pathogens for the agro-food and pharmaceutical industries. The factory and R&D center was then created in his ancestor’s village in the south of France to start an industrial revival.
His sons, Emmanuel and Jules started working with him and today run the company together.
