Thermo Electron Corporation (NYSE: TMO) (incorporated 1956) was a major provider of analytical instruments and services for a variety of domains. It was built by George Hatsopoulos, John Hatsopoulos, and Arvin Smith. On May 14, 2006, Thermo and Fisher Scientific announced that they would merge in a tax-free, stock-for-stock exchange. The merged company became Thermo Fisher Scientific. On November 9, 2006, the companies announced that the merger had been completed. However, the Federal Trade Commission ruled that this acquisition was anticompetitive with regard to centrifugal evaporators, requiring Fisher to divest Genevac. In April 2007, Genevac was sold to Riverlake Partners LLC and the merger closed with FTC approval.[
