Hanson Research, an innovative leader in the design and manufacturing of dissolution testing and diffusion testing instruments for the pharmaceutical industry.
Hanson Research, founded in 1951 by Dr. William A. (“Bill") Hanson, designed and manufactured the world's first six-vessel dissolution testers in 1969, and the first fully automated dissolution testing system, the Dissograph, in 1975. Widespread adoption of Hanson's technology along with an extensive support network made Hanson a trusted supplier for pharmaceutical development and manufacturing lab facilities in 75 countries worldwide. In the diffusion-testing line, focused on transdermal drug formulations, Hanson's innovative vertical diffusion cell, a modified Franz cell, led the way, eventually becoming officially incorporated into the United States Pharmacopoeia (USP) as “Apparatus A." Hanson's Microette™ automated diffusion testing system was first released in 2000, and an advanced design in 2014.
