About Us

Since 1924, Tsutsui has been trusted to provide outstanding, high-quality scientific instruments to a wide range of clients with diverse powder and bulk solids needs throughout the world. We pride ourselves on our commitment to our customers and their specific needs; Our highest priority is our customers’ success.

In 1924, Nitaro Tsutsui established Tsutsui Scientific Instruments Shop in Japan. At this time, the company connected industry professionals to lab equipment made by other companies. After 24 years of success, Tsutsui expanded its scope: we began in-house manufacturing our own instruments as Tsutsui Scientific Instruments Co., Ltd. This has given us a better eye on quality control and the ability to customize our instruments, better addressing our valued customers' needs.
