On May 24, 2017, Pion Inc. acquired Sirius Analytical Instruments. Over the next several months, we will be combining these two great companies under the Pion name. Please bear with us as we go through this transition, merging the two websites and capitalizing on the best parts of both organizations.

Trusted by 20 out of the top 20 Pharmaceutical companies, Pion specializes in the measurement of solubility, dissolution, and ionization for the drug development scientist. Our methods and expertise allows for characterization of drug compounds using API-sparing methods which identify and focus resources.
