Waltham-based mass spectrometer and instrumentation company Thermo Fisher Scientific Inc. has opened the China Technology Center in Shanghai to meet the needs of a growing Chinese customer base.

The tech center is designed to support engineers and development staff in the fields of life sciences, environmental monitoring and consumer product safety.

The company is also opening a demonstration center in Beijing this month, adding to its already established demonstration center in Shanghai, a city that boasts major outposts of seven of the largest global pharmaceutical companies.

Thermo Fisher has a 30-year history of working in China, and its growth in recent years has led to a Chinese version of the company’s product catalog and the new headquarters of Thermo Fisher’s environmental instruments business, where company president and CEO Marc Casper has said he believes business will double in the next five years.

In February, Casper told Mass High Tech, “The Chinese government is pouring millions into food safety and air quality monitoring programs, and we are benefiting from that.”

Thermo Fisher has been leading an acquisitions spree that added four new companies in the time from January to May. The buyouts come as the company has closed, or is in the process of closing, 20 facilities worldwide, amid a restructuring program announced at the end of 2008.  However, last week, the company also confirmed plans to shutter its East Providence, R.I.-based facility, leaving 66 people unemployed.
