PERCIVAL SCIENTIFIC INCORPORATED

Percival Scientific Incorporated specializes in the design and manufacturing of precision environmental control systems for scientific and government research applications. Their core capabilities center on the engineering of biological incubators, growth chambers, and climate-controlled instrumentation that replicate stringent environmental conditions for plant, insect, algal, and microbial studies. The company excels in customizing temperature, humidity, light spectrum, and CO₂ regulation systems to meet the exacting demands of containment labs, quarantine facilities, and agricultural research environments. Their technical expertise includes programmable environmental sequencing, secure containment integration, and compliance with biosafety and experimental reproducibility standards, making them a trusted provider for high-sensitivity life science applications. The contractor maintains consistent relationships with the Department of Agriculture, supporting plant quarantine, insect containment, and micropropagation research; the Department of Health and Human Services, supplying biological incubators for pathogen and cell culture studies; and the Department of Defense, delivering environmental chambers for entomological, algal, and biomedical experimentation. These agencies rely on Percival’s systems for mission-critical research requiring stable, repeatable, and monitored growth conditions. Their primary industry focus lies in air-conditioning and warm air heating equipment manufacturing—specifically for laboratory-grade environmental systems—and analytical laboratory instrument manufacturing, where they produce precision-controlled growth chambers used in genomics, pest management, and ecological research. This positions them as a niche supplier to federal life sciences and agricultural research communities. Percival Scientific Incorporated is a small business based in Perry, Iowa, operating under a 2L entity structure. While they hold no formal government certifications, their reputation is built on decades of engineering precision, regulatory-compliant design, and direct support to federal research missions requiring validated environmental control solutions.
