Parr Instrument Company

Parr Instrument Company, a Moline, Illinois-based manufacturer of high-precision laboratory and scientific equipment, operates as a small business prime contractor (99% of recent awards) supplying pressure vessels, reactor systems, calorimeters, and specialized analytical instrumentation to federal research and development agencies under total small business set-asides and full-and-open purchase orders. The company is a Subchapter S Corporation with SAM.gov registration dating to 2001 and operates primarily under NAICS 334516 (Analytical Laboratory Instrument Manufacturing) and PSC 6640 (Laboratory Equipment and Supplies), with secondary footprint in miscellaneous machinery manufacturing and process-control instrumentation.

Parr Instrument Company's customer base spans 60 distinct federal agencies, heavily concentrated in defense research and civilian energy and agricultural research. The top five customers by award count account for 33% of recent awards: Naval Sea Systems Command (23 awards, $341 thousand combined potential value), the Office of Naval Research (11 awards, $299 thousand), the Agricultural Research Service (8 awards, $233 thousand), the National Energy Technology Laboratory (8 awards, $48 thousand), and the Department of Energy's Office of Fossil Energy (8 awards, $800 thousand). By dollar value, the concentration shifts slightly toward DOE: the Office of Fossil Energy anchors 48% of combined potential value across the top five customers. Recent representative work includes a $440,790 purchase order from DOE's Office of Fossil Energy for a Subsurface Sensor Scale-Up Reactor Series 4559-40L floor-stand reactor system (award date September 22, 2026, completion December 31, 2026), a $117,015 purchase order from Army Research, Development and Engineering Command for a laboratory-scale continuous gas/liquid flow tubular reactor system (awarded December 14, 2023), and a $24,396 total small business purchase order from Naval Sea Systems Command for oxygen combustion analysis equipment including chlorine-resistant vessels and platinum components (awarded September 16, 2025).

The award portfolio shows modest activity in recent years — three awards in 2022, four in 2023, one in 2024, three in 2025, and three in 2026 — with a combined potential value of $4.2 million across 176 total awards spanning back to 1982. Two awards with combined potential value of $457 thousand face ultimate completion within the next twenty-four months. The vendor participates minimally in parent vehicles; historical task orders appear under Army BPA DAAD0582M9782, an Army Indefinite Delivery Contract (DAAG3682M2466), and a Navy Indefinite Delivery Contract (N0014004D0011). Parr Instrument Company operates almost entirely as a prime — only two sub-awards appear in recent history, both for equipment supply: a May 2026 sub to Battelle Memorial Institute for a 4670 HP/HT reactor, and an April 2024 sub to Valkyrie Enterprises supporting MIT Lincoln Laboratory research equipment procurement. The vendor's positioning is narrow and specialized: it manufactures to order for federal R&D, works on small purchase orders (historical range $13,000 to $440,790), and competes on brand-name mandatory requirements and firm fixed-price commercial-item acquisitions where its proprietary reactor and pressure-vessel designs are sole sources or lowest-price compliant.
