About Percival Scientific

In a time when many companies come and go, Percival Scientific, Inc. has the unique distinction of being in business for over 125 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. Forty years later, in 1941, the company moved to a new 24,000 square foot facility and continued to manufacture a complete line of refrigerated display units. Since May 2000, we’ve occupied a state-of-the-art 60,000 square foot facility in Perry, Iowa.

Percival Scientific, a worldwide leader in the design and manufacture of environmental growth chambers, is proud to call Perry, Iowa our home. Our facility encompasses all engineering, design, fabrication and construction of our extensive product line, allowing Percival Scientific to maintain complete control of the manufacturing process.

Percival chambers have become the preferred choice among universities, colleges, government institutions and businesses both domestically and internationally. Our chambers are found in Europe, Asia, Brazil, India, China, Australia as well as many other countries. Our ability to meet individual requirements and to control multiple critical testing variables is what has allowed Percival Scientific to become an industry leader.
