Whittaker Corp. has purchased a medical-test making division of Minnesota Mining and Manufacturing and intends to merge its operations into Whittaker's biotechnology unit that is based in Maryland.
Whittaker, an aerospace and biotechnology firm based in Los Angeles, purchased 3M Diagnostic Systems for about $8
million plus deferred payments totaling $3.4 million.
The diagnostics unit, which makes test kits for allergies and Lyme disease, will be moved from Santa Clara, Calif., to Walkersville, near Frederick, Whittaker said.
The 3M unit employs about 90 people, but not all of them will be needed at the combined operation, said Edward R. Muller, spokesman for Whittaker. He said the company could not estimate how many jobs will be added at the Walkersville site, which now employs about 400.
