Since 1990, LOGAN is dedicated to the design, development, production, sales, and service of manual and automated drug dissolution systems. LOGAN is one of the very few companies that manufacture all USP Apparatuses 1-7. Logan Instruments' products have been used for three decades by top pharmaceutical companies on five continents with customers in more than 60 countries around the world. LOGAN has become a significant supplier for drug dissolution testing in the pharmaceutical industry.

In the early 1990s, LOGAN developed its transdermal diffusion system for scientific research. Now, LOGAN’s transdermal diffusion systems have widely been utilized by top pharmaceutical and cosmetic companies, chemical manufacturers, CRO’s, and universities around the world. At about the turn of the millennium, LOGAN designed its first generation dry-heated transdermal cell. It was soon recognized and adopted by the industry and academia. As a result, the dry-heated transdermal cells have since graced benches of the many well-known pharmaceutical factories and R&D institutes in Europe and the United States.
