Eurofins Agroscience Services offers a broad spectrum of analytical services needed for the registration of your substances

For each source of an active substance, a technical specification is required - we can generate data on the physical, chemical and technical properties of plant protection products and other chemicals as detailed in the relevant regulations and guidelines.
