Percival Scientific’s chambers and incubators have features not offered by any other company and are the preferred choice of universities, colleges, government institutions and private firms in all 50 states and throughout the world.

Originally established in 1886, by C.L. Percival and J.E. Smith, Percival Manufacturing in Des Moines, Iowa, initially 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 sq. ft. facility and continued to 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. Additionally, Percival recently partnered with Iowa State University’s Department of Engineering to create a highly resourceful incubator control package that is an exclusive product in the industry.

From its beginning on the Central Iowa Plains, Percival Scientific has grown to represent a rich tradition of product ingenuity and reliability throughout the world. With a history that spans more than a century, Percival will continue its commitment to improving research methods that will impact tomorrow.
