Taiatsu Techno Corporation

Taiatsu Techno Corporation (耐圧硝子工業株式会社) is a Japanese manufacturer specializing in the design and production of high-pressure vessels and related laboratory equipment. The company traces its origins to 1949, when it was established as a dealer of scientific and chemical instruments. In 1964 it adopted its current name, Taiatsu Glass Industry Co., Ltd., reflecting its focus on pressure-resistant glass (耐圧硝子). The term "taiatsu glass" itself derives from pressure-resistant glass tubes developed at Tohoku University's Non-Aqueous Solution Chemistry Laboratory (now the Institute of Multidisciplinary Research for Advanced Materials) for experiments involving liquid ammonia and similar substances. The company's product portfolio is organized into four main categories: glass products, metal products, PTFE products, and high-pressure experimental equipment. Its flagship glass product is the Hyper Glass Cylinder (HPG type), a transparent pressure vessel used for hydrogenation, synthesis reactions, refrigerant and refrigeration oil testing, and as a dropping container. Metal products include the TVS series of portable reactors, available in various volumes and pressure ratings up to 20 MPa, as well as the TEM-D metal reaction apparatus. PTFE-lined vessels such as the TAF-SR and TAF-R1500 are designed for durability and corrosion testing where sample contamination by metal ions must be avoided. The company also produces supercritical fluid observation cells and compact supercritical CO2 processing vessels. Taiatsu Techno Corporation operates from Bunkyō-ku, Tokyo, and serves research institutions, universities, and industrial laboratories. Its products are used in fields such as hydrogenation, hydrothermal synthesis, supercritical fluid research, and corrosion testing. The company emphasizes the advantages of pressure-resistant glass vessels—high corrosion resistance and visual transparency—and continuously improves them for diverse research applications. In 1994 it established the Taiatsu Technical Research Institute, integrating design, development, and manufacturing divisions, and commercialized the Hyper Glass Cylinder. In 1999 it launched a windowed reaction vessel for supercritical fluid research (supercritical observation cell), which has been well received by researchers. As of the company's 2015 message, the representative director was Motoyuki Watanabe. The company remains a privately held entity and is not listed on any stock exchange. It continues to develop and manufacture custom high-pressure equipment, including first-class and second-class pressure vessels, high-pressure gas specific equipment, and lab-scale mini plants.

Taiatsu Techno Corporation was founded in 1949 (Showa 24) as a company selling scientific and chemical instruments and apparatus. In 1964 (Showa 39), it changed its name to Taiatsu Glass Industry Co., Ltd. (耐圧硝子工業株式会社), marking a shift toward manufacturing pressure-resistant glass products. The name "taiatsu glass" (耐圧硝子) originates from pressure-resistant glass tubes devised at Tohoku University's Non-Aqueous Solution Chemistry Laboratory (now the Institute of Multidisciplinary Research for Advanced Materials) for experiments with liquid ammonia and similar substances. Over the decades, the company expanded its expertise beyond glass to include metal high-pressure vessels and lab-scale mini plants. In 1994 (Heisei 6), it established the Taiatsu Technical Research Institute, integrating its design and development division with its manufacturing division, and commercialized the Hyper Glass Cylinder, a glass pressure vessel. In 1999 (Heisei 11), it commercialized a windowed reaction vessel for supercritical fluid research (supercritical observation cell), which gained popularity among researchers. The company has continued to develop and improve its product lines, including portable reactors, PTFE-lined vessels, and supercritical CO2 processing equipment. As of March 2015, the representative director was Motoyuki Watanabe. The company remains privately held and operates from Bunkyō-ku, Tokyo.
