The company released the Photometric Titralyzer that year, and a Hem-alyzer in 1968. In 1968, it purchased Massachusetts-based Jarrell-Ash Company, a producer of optical instrumentation, particularly for emission and atomic absorption spectroscopy. It acquired Chicago-based Stansi Scientific Company in 1967, expanding into educational science supplies. In 1976, Fisher Scientific established an Instrument Service Division. Fisher was acquired by Morristown, New Jersey-based Allied Corporation in 1981 for $330 million. At this time Benjamin R. Fisher was Chairman of the company, having gained the position in 1975 upon Aiken's retirement. Operating as a subsidiary of Allied Corporation (and later AlliedSignal Inc., and The Henley Group), Fisher established a Biotechnology Division in 1985. In 1991, The Henley Group sold a majority interest in Fisher through a public stock offering. The public entity was called Fisher Scientific International Inc., and based in Hampton, New Hampshire. Fisher Scientific Company remained in Pittsburgh as an operating subsidiary. In 1992, Fisher facilities were ISO-9000 certified. In the 1990s, Fisher, with partner Intertech Corporation of Atkinson, New Hampshire, set up a pharmaceutical testing and certification lab in Moscow, Russia, to serve with the Russian Federation's Ministry of Health and Medical Industry needs. Fisher acquired Eastman Kodak Company's organic-chemicals business and Janssen Chimica, forming Acros Organics. In August 2004, the company merged with Apogent Technologies Inc., a company engaged primarily in the manufacture and sale of laboratory products in the United States and other countries. In May 2006, Fisher Scientific and Thermo Electron announced that they would merge in a tax-free, stock-for-stock exchange. The merger closed on November 9, 2006 and the merged company is now called Thermo Fisher Scientific. The merger was valued at $12.8 billion.
