San Diego-based laboratory software provider Accelrys Inc. has purchased Swiss biosciences systems integrator Vialis AG for $5 million in cash.

Accelrys bought all of Vialis’ outstanding stock, and the acquisition includes potential for an additional $5 million in incentives, contingent upon Vialis meeting certain milestones over the next three years. Vialis’ entire staff, based in Liestal, Switzerland, will join Accelrys, the companies said in a joint statement.

“As a long-standing partner, we share Accelrys’ vision of transforming the innovation lifecycle by delivering paperless laboratory solutions that enhance our customers’ abilities to meet the operational challenges that are slowing scientific innovation," said Vialis CEO Ulf Fuchslueger in a statement.

Last October, Accelrys acquired Lafayette, Col.-based Aegis Analytical Corp. for $30 million in cash. The company’s Discoverant software aggregates, contextualizes and analyzes manufacturing, quality and development data to allow manufacturers to predict the outcomes of their processes.

And in January 2012, Accelrys acquired Hopkinton, Mass.-based Velquest Corp. for $35 million in cash. The company develops software that captures data from scientific instruments for pharmaceutical and medical device manufacturers.

Accelrys President and CEO Max Carnecchia said in a statement that the company’s growth strategy through these three recent acquisitions is to “deliver software solutions that optimize the laboratory-to-commercialization value chain.”
