"We are excited about our ability to provide an expanded portfolio of products and services, as well as increased distribution capabilities to meet the current and future requirements of our customers in Puerto Rico and elsewhere," said Walter W. Zywottek, VWR president and chief executive officer. "The broad portfolio of products and services within Advanced Instruments' brands are extremely complementary with VWR's product offering and distribution capabilities, creating important synergies and value for all of our customers."

VWR's investment in the Puerto Rican marketplace will include more than tripling the capacity of the general distribution warehouse, significant expansion of the environmentally controlled hazardous chemical storage capabilities, increased capabilities within the metrology and technical laboratory services, and an increase in the workforce to support the expanding services business.

"These investments will have a positive impact on the local economy and signify our long-term commitment to the Puerto Rican marketplace," said Zywottek.

Carlos M. Rodriguez, current president of Advanced Instruments' Group of Companies, will lead the new combined organization in Puerto Rico. According to Rodriguez: "The combined organization will provide customers with significant synergies that will help them improve their own efficiencies. For the first time customers will enjoy the benefits of having a single premier distributor with an expanded product offering, asset management and analytical services.
