Pion utilizes advanced fiber optics for in situ kinetic solubility and supersaturation UV monitoring for dissolution testing to determine the rate of release of a drug substance over time. Pion delivers fast and reproducible results for testing of API's and formulations in bio-relevant media. These measurements are accurate, even with small volumes and complex matrices. From pure API, to formulations, to finished QC drug product, Pion can meet the need of every scientist along the drug development cycle.
