Physicochemical and Technical Properties

Mérieux NutriSciences offers a whole set of tests suitable for evaluating the physical and chemical properties of technical products, or active substances, and formulated products. Our experts are equipped to perform a broad range of studies needed for the registration of agrochemicals and plant protection products. These include fertilizers as well as biocides such as disinfectants, preservatives, pest control and other biocidal products.

We provide the following tests according to your needs:
