Who Owns Thermo Scientific?

The Thermo Scientific brand traces to Thermo Electron Corporation, founded in 1956 in Belmont, Massachusetts, by George Hatsopoulos and Peter Nomikos. Thermo Electron grew through acquisitions into a broad instrument maker covering environmental monitoring, analytical chemistry, and process control.

When Thermo Electron merged with Fisher Scientific in November 2006, the combined company adopted the Thermo Scientific brand for the instrument and laboratory products portfolio. Fisher Scientific continued as the distribution and supplies channel, while Thermo Scientific became the nameplate on manufactured instruments and equipment.

The brand absorbed additional product lines through Thermo Fisher's acquisition strategy. Mass spectrometry systems from Finnigan, chromatography from Dionex (acquired 2011), electron microscopy from FEI (acquired 2016), and biosciences tools from Life Technologies (acquired 2014) all came under the Thermo Scientific umbrella. Flagship platforms include Orbitrap mass spectrometers, Krios cryo-electron microscopes used in structural biology Nobel Prize-winning work, and Dionex chromatography systems.

During the COVID-19 pandemic, Thermo Scientific instruments and consumables were central to testing and vaccine development. In 2025, the company continued launching new platforms under the brand, including next-generation mass spectrometry systems for proteomics research, and expanded bioprocessing equipment through the acquisition of Solventum's purification and filtration business.
