Pioneering since 1993

Hidex Oy was founded in 1993 by Jukka Haaslahti and Marja-Liisa Haaslahti. Soon after, the company was joined by accomplished engineers Juhani Aalto and Timo Oikari as Co-founders. The pioneers set out to achieve an ambitious target – the development of the world’s first portable liquid scintillation counter. The launch of the world's first portable LSC, the Hidex Triathler, resulted in the company gaining recognition in the liquid scintillation counting community. This was the first of many milestones for the company that recently celebrated its 30th anniversary. The company currently employs close to 40 professionals, has active distribution in more than 30 countries and has roughly 5000 instruments in service worldwide.
