Scientific Firsts

tousimis research corporation was one of the first laboratories designed to provide instruments, chemicals, reference standards, and laboratory accessories specifically for the electron microscopy laboratory and X-ray micro analysis research service. Dr. A. J. Tousimis and colleagues have made extraordinary discoveries and reached many milestones in the field of science throughout the years, some before our company was even established. Dr. Tousimis has written two books and authored more than 149 publications. Here are a few of the revolutionary breakthroughs that tousimis research corporation is proud to boast:
