Nissui Pharmaceutical

Shimadzu Diagnostics Corporation, formerly known as Nissui Pharmaceutical, is a prominent Japanese healthcare company specializing in microbiology and clinical diagnostics. The company is a global leader in the production of culture media, most notably its "CompactDry" line of ready-to-use dry plates used extensively for food safety and environmental testing. Beyond microbiology, the firm develops and manufactures clinical diagnostic reagents for infectious diseases and maintains a portfolio of over-the-counter (OTC) pharmaceutical products. Following its acquisition by Shimadzu Corporation in 2022, the company was renamed in 2023 to reflect its integration into Shimadzu's analytical and medical business segments. It continues to innovate in automated testing solutions, leveraging technologies such as the @BactLAB AI-based colony counter.
