About the Company

Eurofins

Global lab testing and analytics network

Eurofins provides global laboratory testing and analytical services to verify the safety, authenticity, and quality of products across food, water, medicine, and the environment. It operates a network of more than 900 laboratories in over 60 countries, offering access to more than 200,000 analytical methods. Its product work involves running specialized tests—using chemistry, biology, and other scientific techniques—to confirm origin, composition, and compliance of samples, such as detecting wine fraud or contaminant presence. The company differentiates itself through its massive, distributed lab network and broad portfolio, enabling standardized testing at scale and fast turnaround across many industries, rather than relying on a single specialty or location. Its goal is to protect public health and safety by delivering accurate, comprehensive testing data and helping clients meet regulatory and quality requirements.
