Thermo Electron Corporation was a major provider of analytical instruments and services for a variety of domains. It was co-founded in 1956 by George N. Hatsopoulos, an MIT PhD in mechanical engineering, and Peter M. Nomikos, a Harvard Business School graduate, who provided initial funding.
Fisher Scientific International, Inc. was a laboratory supply and biotechnology company that provided products and services to the global scientific research and clinical laboratory markets until its merger with Thermo Electron in 2006, after which it became Thermo Fisher Scientific. The company offered products and services to over 350,000 customers located in approximately 150 countries including pharmaceutical and biotechnology companies, secondary and higher education institutions, hospitals and medical research institutions, and quality control, process control and research and development laboratories.
Simmons' citrate agar is used for differentiating gram-negative bacteria on the basis of citrate utilization, especially for distinguishing Gammaproteobacteria of the family Enterobacteriaceae or even between species of the same genus. For example, Salmonella enteritidis would yield a positive (blue) result on Simmons’ agar and thus be distinguished from other Salmonella species like Salmonella typhi, Salmonella pullorum, and Salmonella gallinarum, which would yield a negative (green) result.
Thermo Fisher Scientific Inc. is an American-headquartered life science and clinical research company. It is a global supplier of analytical instruments, clinical development solutions, specialty diagnostics, laboratory, pharmaceutical and biotechnology services. Based in Waltham, Massachusetts, Thermo Fisher was formed through the merger of Thermo Electron and Fisher Scientific in 2006. Thermo Fisher Scientific has acquired other reagent, consumable, instrumentation, and service providers, including Life Technologies Corporation (2013), Alfa Aesar (2015), Affymetrix (2016), FEI Company (2016), BD Advanced Bioprocessing (2018), and PPD (2021).
Alfa Aesar was a supplier of reagents and materials for use in research and development, and analysis. The company had facilities in a variety of countries and manufactured many of the chemicals they sold. The company was bought by Thermo Fisher Scientific in 2015, having previously existed as part of the Johnson Matthey Fine Chemicals & Catalysts Division. In 2021, Alfa Aesar products were rebranded under the Thermo Scientific brand name.
Pharmaceutical Product Development (PPD) is a global contract research organization (CRO) providing comprehensive, integrated drug development, laboratory and lifecycle management services. In December 2021, PPD became a wholly owned subsidiary of Thermo Fisher Scientific.
Ammonium fluorosilicate (also known as ammonium hexafluorosilicate, ammonium fluosilicate or ammonium silicofluoride) has the formula (NH4)2SiF6. It is a toxic chemical, like all salts of fluorosilicic acid. It is made of white crystals, which have at least three polymorphs and appears in nature as rare minerals cryptohalite or bararite.
Pierce Biotechnology Inc. is the ultimate origin of a number of products and product lines in the Thermo Fisher Scientific research and development division, "Thermo Scientific Pierce Protein Biology." The company from which this division originated, the Rockford, Illinois-based Pierce Chemical Company (PCC) was founded in 1948 when Alan Pierce assumed active management of a company known as Midwest Extraction, which focused on isolating chlorophyll from alfalfa.
