Midwest Special Instruments Corp

Midwest Special Instruments Corp, a for-profit Subchapter S corporation based in Prior Lake, Minnesota, distributes, installs, calibrates, and maintains audiology and vestibular diagnostic equipment to the federal healthcare system as a prime contractor only, competing predominantly under small business set-asides. The company operates as an authorized distributor for Interacoustics, GSI, Audioscan, and Micromedical equipment and holds manufacturer-trained service credentials across these brands.

The Department of Veterans Affairs dominates Midwest Special's customer base, accounting for 28 awards (85% of recent volume, $2.7 million combined potential value). Within VA, Veterans Integrated Service Network 23 (VISN 23) serves as the anchor customer with 23 awards valued at $1.8 million, covering audiology equipment procurement, calibration, maintenance, repair, and sound room certification at VA medical centers across Iowa, Nebraska, North Dakota, and South Dakota. The Department of Health and Human Services Indian Health Service contributes four awards ($66 thousand combined potential value) for hearing aid analyzers and audiology equipment. The South Dakota Army National Guard and the U.S. Coast Guard round out the customer roster with single-award purchases. Top capability examples include a $287.8 thousand full vestibular testing system to VISN 23 (May 2024), a $259.6 thousand procurement of 19 Interacoustics Titan V4 tympanometers with DPOAE capabilities to Minneapolis VA Medical Center (August 2022), and a $117.5 thousand Orion Rotary Chair system with integrated diagnostic equipment to Nebraska-Western Iowa VA Healthcare System (July 2025).

Midwest Special holds a single-award indefinite-delivery contract with VA (ceiling $479.4 thousand through July 2030) for audiology equipment calibrations, maintenance, and support across VISN 23's region. Two delivery orders have been issued under this vehicle: $54.4 thousand for audiology maintenance support (August 2025–July 2026) and $104 thousand for calibrations and maintenance (August 2026–July 2027). Recent award activity shows growth — three awards in 2023 and 2025 to five in 2026 — though the portfolio remains concentrated geographically and by customer. Four awards (combined potential value $490 thousand) complete within the next twenty-four months and face recompete risk. Award scope centers on medical and surgical instruments (NAICS electromedical and electrotherapeutic apparatus manufacturing; PSC medical and surgical instruments), with work performed primarily in Minnesota and South Dakota.
