APRIORI Corporation was founded in May 1983 at Kanda-kajicho,Chiyoda-ku, Tokyo Japan.
The founder had been a sales engineer of the fluid controls in the importers for heavy industries such as space, nuclear, ocean, military armament, ferrous and non-ferrous industries.
So, he mainly handled sophisticated US products and learned engineering and sales know-how. Moreover, he was fortunate to have had an opportunity to join most of the national projects of our country. He has full of knowledge and experience especially in High pressure, High Temperature and Cryogenic handling requirement.
At the foundation of APRIORI, semi-conductor manufacturing industry was about to boom, therefore, business target of APRIORI was aimed at fluid controls in association with the semi-conductor production.
Furthermore, APRIORI started development & manufacturing of thin-film deposition system and chemical reaction control system as truly excellent engineers have joined.
Since the foundation, APRIORI has been a dealer of STEC(Standard Technology Inc.) Mass Flow Controller. This product was not famous, but now STEC(HORIBAstec) is the top maker of Mass Flow Controller in the world and APRIORI is the top dealer.
Moreover, APRIORI had been acting as the exclusive representative of Thomas Swan & Co.,Ltd.(U.K)-Semi Div.(MOCVD System and Gas Concentration Monitor).
Thomas Swan’s Semi division was totally nameless company at the beginning but became a world-famous semiconductor tool manufacturer as sales grown in Japan. The founder of division sold this successful division to German company as he retired for his age. Since this German company competes our Japanese customers, Apriori decided to withdraw from this business at the end. (1985-2002)
Thomas Swan Ltd. is currently the world-leader in Chemical industry and still providing excellent and outstanding quality products in the market.
APRIORI had became the exclusive representative of Lorex Industries, Inc.(USA) in September 2002.
The sales partnership had been continued until Lorex was acquired by Veeco Instruments Inc.(USA) in April 2011 and APRIORI had finished the exculsive representative.
Lorex industries' Gas Concentration Monitor was just the nameless product at the beginning but became World-standard Gas Concentration Monitor as sales grown in Japan, however history repeats itself, Lorex Industries was acquired by American company in 2011 and Apriori decide to withdraw from this business since this American company competes our Japanese customers again. (2002-2011)
APRIORI’s mission is to offer product & service, which is supported by the high level of technologies to the dramatically changing fields as New energy, Pharmastical and Electronic Device industry.
“APRIORI Brings you Technology Science” is the catch-phrase of APRIORI.
