CEM

Scientists, mad or otherwise, probably love to browse CEM's product catalog. CEM -- short for chemistry, electronics, and mechanics -- makes microwave-based instruments that perform testing, analysis, and process control in laboratory and industrial environments. The company's MARS heating system analyzes samples by dissolving them in acid. CEM's other products include moisture/solids analysis systems and fat analyzers. CEM sells directly in the US and worldwide through subsidiaries and distributors in about 50 countries. It serves such industries as food, tobacco to plastics, chemicals, and textiles. Established in 1978, CEM was taken private in 2000 by founder and CEO Michael J. Collins.
