Key Employers - Percival Scientific, Inc.
Percival Scientific, Inc. has the unique distinction in being in business for over 120 years. In 1886, C.L. Percival and J.E. Smith established Percival Manufacturing in Des Moines, Iowa. Initially, the company manufactured and sold butcher tools, machinery and fixtures. By 1901, the need for a refrigerated cabinet became evident, prompting Percival to pursue and receive a patent and manufacture a complete line of refrigerated display units.

In the early 1950’s, at the request of Iowa State University Percival became involved in creating the first commercially available plant growth chamber. This began the company’s tradition of designing and manufacturing chambers that control the environment for specific research applications.

In 1999, when Percival Scientific was looking to build a new office and production facility, our search criteria centered on communities that had readily available and developed sites, a well educated workforce and the infrastructure to support our manufacturing requirements.

After meeting with members of Perry Industries, Perry Economic Development, Greater Dallas County Development Alliance and other local leaders, it was clear that the City of Perry met and exceeded all of our search criteria.

The decision to relocate to Perry was made in September 1999 and the official opening of our new facility was May 1, 2000.

Today, Percival Scientific continues to set the standard of excellence for the environmental control industry and occupies over 60,000 square feet of manufacturing space in Perry dedicated to the production of over 75 different models of plant growth chambers, biological incubators, environmental rooms, and chambers that support special research applications. Percival Scientific provides options that are unique and the preferred choice of universities, colleges, government institutions, and biotechnology companies in the United States and throughout the world. Innovation of superior control of temperature, humidity and lighting has kept Percival at the forefront of the industry and will help Percival’s growth in the future.

Currently, Percival has over 75 employees in the manufacturing facility and in addition sales representation in the United States and Internationally. The President and CFO is Gary Wheelock, Henry Imberti is Vice President of Engineering, Cris Hulse is the Production Manager, Joni Campidilli is Director of Sales & Marketing, and Mitch Yates is Percival’s Purchasing Manager.

With a history that spans more than a century, Percival will continue it commitment to improving research methods that will impact tomorrow.
