History
The Diapharma Group, Inc. formed on January 1, 1997 from Pharmacia Hepar, Inc. in Franklin, Ohio, and began as the exclusive US and Canadian distributor of the Chromogenix substrates and assays.
Over a quarter-century ago, Chromogenix developed the first chromogenic substrate technology under the former name, Kabi Diagnostica. Kabi later merged with Pharmacia. Some of Diapharma’s current staff worked inside the Chromogenix department within Pharmacia’s heparin manufacturing plant.
In 1998, Diapharma moved to West Chester, Ohio, where it remains today. Over the years, Diapharma expanded its product line to include a variety of hemostasis, cell death, platelet function, ecotoxicology, assays, reagents, antibodies and instruments from superior manufacturers.
In 2017, Diapharma celebrated twenty years of success
