Physicochemical Characterization, Analytical Chemistry & Stability Testing

Physicochemical Characterization
Physicochemical testing is an integral requirement of product registration for agrochemicals. Charles River offers all the characterization and physicochemical studies (active ingredients and formulated products) necessary to support registration worldwide.

Analytical Chemistry
Experienced analysts are available to establish new analytical methods or to transfer existing methodology using a wide range of up-to-date equipment.

Stability Testing
The storage stability and shelf-life of the formulated product can be determined under a variety of specified storage conditions. Solid, liquid, semi-solid and aerosol formulations can all be evaluated using real-time and accelerated storage stability testing. We have dedicated facilities to stress the material using monitored heat, humidity or light parameters.
