Alexeter Technologies LLC is a privately held company, specializing in the development and direct delivery of commercial biological defense systems, located in the suburbs of Chicago, Illinois. We were formed in the late 1990's to address the pressing need for rapid & reliable on-site equipment for collecting and identifying biological threats in the environment.

The recognized leader in commercial biological defense, our clients include Fortune 500 firms in the industrial, financial, transportation, pharmaceutical, entertainment and technological industries. We supplied the Guardian Reader System well before the anthrax attacks of September 2001, and our products are currently in use in hundreds of federal, state and municipal response units throughout the United States.

Years of research and field experience are incorporated into our next-generation, patent-pending product designs, and we continue to develop leading-edge technology for the rapid detection of biological agents.
