Happy Birthday, Laboratoires Dujardin-Salleron!20 / 03 / 2025
This year, Dujardin-Salleron Laboratories proudly celebrate 170 years of existence. Our founders were visionaries who revolutionized oenological analysis, and we continue this momentum today. LDS is a French company, strong in its history and expertise, focused on the future, capable of innovating, and ready to face tomorrow's challenges with ambition and determination.
Once upon a time...
Inspired by the work of Pasteur, Jules Salleron dedicated his research to the study of fermentation and the determination of alcohol content.
In 1855, he founded a company specializing in precision instruments in Paris and invented a still meter, which is still used today.
In 1880, Jules Dujardin joined the company. He took over in 1889 and combined his name with Salleron’s to form the Dujardin-Salleron Establishments.
Although the company became Laboratoires Dujardin-Salleron in 1987 and left the family ownership, it did so to excel in precision instrumentation for oenology and spirits. The headquarters moved within Paris, then to the Parisian suburbs in Arcueil in 1994.
In 2003, Laurent Dubreuil, the current president, acquired Laboratoires Dujardin-Salleron. From the outset, a quality approach was implemented, leading to the ISO 9001 certification in 2005. In 2008, he acquired the Verrerie Scientifique et Technique Dumas. One of the objectives is to ensure local and autonomous production of glass parts essential for LDS instruments. In 2010, the activities of Laboratoires Dujardin-Salleron were transferred to Noizay in Indre-et-Loire, on the same site as Verrerie Dumas, enabling synergies. In 2018, the acquisition of Fabre, the last French manufacturer of refractometers, aimed to preserve recognized national expertise, diversify LDS's activities in other food sectors, and strengthen market shares in the face of international competition.
Today, the company remains a reference in the field of precision instrumentation thanks to its constant demands and its investment in R&D. While beginning its ecological and energy transition, Laboratoires Dujardin-Salleron continues to innovate, particularly through its integrated design office, which anticipates the needs of sectors and ensures the design of excellent professional equipments.

Innovation is embedded in our company’s DNA.
From the moment he entered the industrial world, Jules Salleron was passionate about certain issues related to alcoholic liquids. In 1853, he developed a still that was quickly adopted by the Ministry of Finance, which had previously used Gay-Lussac’s model. Salleron's invention, more compact and capable of determining the alcohol content with just 50 cm³ of liquid, met with immediate success and earned him a bronze medal at the 1855 Universal Exhibition. The use of this still became so widespread that the Authorities and the Trade referred to the result obtained as the "Salleron Degree."
This spirit of innovation, deeply rooted in Dujardin-Salleron’s DNA, continues to drive our development, providing tailored technical and commercial solutions—even when they have to be invented. A human-sized company certified ISO 9001 since 2005, we have always prioritized a controlled and responsible design approach for greater efficiency.
Today, our commitment to the energy transition is reflected in a first carbon footprint assessment equivalent to that of a service company—an encouraging result that motivates us to continue innovating toward a more sustainable and environmentally friendly future.
