CEM was established in 1978 by a chemist, an electrical engineer and a mechanical engineer, who designed and produced the first microwave laboratory instrumentation - a moisture/solids analyzer. The chemist, Michael J. Collins, had written his dissertation on microwave spectroscopy and felt certain that there was a market for microwave instrumentation that could produce rapid, accurate results. He was right. In the true spirit of an entrepreneurial inventor, Collins and his colleagues worked from a small building in Matthews, North Carolina, where they helped pioneer the field of microwave chemistry. Within a short time, CEM built a much larger manufacturing facility and began to pursue the international market. Today, the company has grown to include 4 international subsidiaries, a worldwide network of distributors and product lines that now encompass instrumentation for life sciences, analytical applications, and process control.

CEM Corporation, a private company based in Matthews, North Carolina, is the leading provider of microwave laboratory instrumentation. The Company has subsidiaries in the United Kingdom, Germany, Italy and France, as well as a global network of distributors. CEM designs and manufactures systems for life sciences, synthetic chemistry, analytical chemistry, and processing plants worldwide. The Company's products are used in many industries including pharmaceutical, biotech, chemical, environmental, and food processing, as well as for academic research.
