About the company
Percival Scientific Incorporated, doing business as Percival Scientific Inc., manufactures specialized controlled-environment growth chambers, incubators, and tissue culture systems for federal research agencies as a prime contractor, operating as an SBA-certified women-owned small business headquartered in Perry, Iowa. The company competes predominantly in full-and-open federal procurement, with its recent award footprint spanning 880 prime contracts across 64 customer agencies and a single sub-award to Leidos.
Percival Scientific's core capability centers on designing and manufacturing highly customized environmental chambers with precise control of temperature, humidity, lighting, and atmospheric conditions to support agricultural, microbiological, plant biology, and related research. Representative work includes a $518,900 total small business set-aside purchase order from USDA's Agricultural Research Service for three walk-in growth chambers with site preparation and installation in Charleston, South Carolina (awarded August 2025); a $243,950 total small business set-aside order from USDA ARS Pacific West Area for walk-in growth chambers for plant and insect research in Wapato, Washington (August 2024); and a $602,278.70 delivery order from USDA ARS for reach-in environmental chambers to maintain live insect colonies in Perry, Iowa (August 2022). The company also supplies individual specialized units across product lines—plant growth chambers, seed germination chambers, biological incubators, dew formation chambers, tissue culture chambers, and algae growth chambers—each configured to customer specifications.
Customer concentration is heavily skewed toward USDA's Agricultural Research Service Field Research Implementation and Information Delivery organization and its regional variants (Northeast, Pacific West, Plains, Midwest, and Southeast Areas), which together account for 449 awards with $14.2 million combined potential value across 51% of the award count but represent a concentrated customer base within a single parent agency. Distinct customer agencies number 64, though the top five customer segments—all within USDA ARS Field Research divisions—cover 37% of combined potential value ($5.9 million of $37.9 million total). No other single customer approaches USDA ARS volume; second-tier customers include the National Oceanic and Atmospheric Administration, Environmental Protection Agency, Food and Drug Administration, Department of Defense (primarily the Army Engineer Research and Development Center), National Institutes of Health, USDA Animal and Plant Health Inspection Service, and the Smithsonian Institution, typically placing one to three orders per year each.
Percival Scientific holds seats on the GSA Multiple Award Schedule (MAS), the primary vehicle carrying 415 task orders worth $11.8 million combined potential value; the company also operates under Federal Supply Schedules GS24F0010M (94 task orders, $2 million combined potential value) and GS00F6230A (2 task orders). These are government-wide indefinite-delivery vehicles enabling agencies to issue delivery orders and purchase orders against pre-negotiated rates and terms.
Activity has remained relatively flat over the past five years—39 awards in 2022, 48 in 2023, 49 in 2024, declining to 19 in 2025 and recovering modestly to 23 in 2026—with a total of 881 awards logged since 1992. The recompete window (next twenty-four months) encompasses 19 awards with combined potential value of $1.1 million, representing modest recompete exposure relative to the vendor's overall footprint. Recent awards concentrate in September 2026, with fifteen orders issued in a single month, reflecting procurement cycles at USDA ARS.
Set-aside posture is mixed: across the recent award portfolio, 177 awards (20%) carry total small business set-asides, 14 carry woman-owned small business set-asides, and the remainder are full-and-open or unrestricted procurements. The vendor competes predominantly under full-and-open vehicles, particularly the GSA MAS, though it qualifies for and wins total small business set-aside orders at material frequency and dollar value.
Service Contract Inventory data is sparse—only 2 SCI records, both as a named subcontractor in FY2022 covering 0.5 FTEs—indicating that the vast majority of Percival Scientific's federal revenue derives from product sales (growth chambers, incubators, and related equipment) rather than labor-hour service contracts. The company operates as a goods manufacturer and prime contractor on 100% of awards in the source data, with negligible subcontractor presence; no teaming relationships with other large primes are evident in the award record.
