TSE Systems, Inc.

TSE Systems, Inc., a for-profit manufacturer of specialized biomedical research equipment headquartered in Huntley, Illinois, supplies high-precision physiological monitoring, behavioral testing, and inhalation exposure systems to federal health research agencies as a prime contractor (100% of recent awards), competing exclusively in full-and-open procurements without set-aside designation.

TSE Systems operates as a sole-source vendor of proprietary research instrumentation. The company manufactures IntelliCage behavioral monitoring systems, Stellar implantable telemetry transmitters for cardiac and neurological monitoring, PhenoMaster phenotyping platforms for metabolic and neurotoxicological assessment, RotaRod motor-function testing equipment, kinematic analysis systems, and inhalation exposure units with humidity and mass-flow control. Recent representative work includes a $959 thousand firm fixed-price purchase order (March 2026) from the Veterans Affairs Veterans Integrated Service Network 12 for a PhenoMaster-IntelliCage system integrating 16 phenotyping cages, 4 behavioral test units, and 3 climate chambers to assess military-toxicant exposure effects on neuro-metabolic disease risk; a $544 thousand firm fixed-price purchase order (February 2023) from the FDA for preventative and corrective maintenance and repair services on six TSE inhalation exposure units at the National Center for Toxicological Research in Beltsville, Maryland, running through March 2027; and a $58 thousand sole-source purchase order (January 2026) from the Naval Medical Research Command for Stellar implantable transmitters designed for rat models to support aircraft deicing fluid toxicity research at Wright-Patterson Air Force Base.

TSE Systems' customer base concentrates heavily in civilian health research. The top five customer agencies by potential value account for 76% of all awards, anchored by the FDA (15 awards, $4.6 million combined potential value) and the Department of Veterans Affairs (including Veterans Integrated Service Network 12 with $959 thousand in a single large award), followed by the National Institutes of Health National Institute of Environmental Health Sciences (9 awards, $443 thousand), the Army Medical Command (5 awards, $316 thousand), and the NIH National Institute on Aging (5 awards, $97 thousand). The company serves 28 distinct customer agencies in total. TSE Systems places a small volume of work under an HHS IDV (Indefinite Delivery Contract HHSF223201400028I), which carried two task orders valued at $64 thousand combined.

Activity has been episodic. Five awards closed in 2021; volume contracted to two awards in 2022 and three in 2023, before rising slightly to four awards in 2024 and two in 2026. The combined potential value across 76 awards over the source period stands at $9.1 million, with $8.7 million obligated (96% of ceiling). One award (the FDA inhalation unit maintenance contract valued at $545 thousand) faces ultimate completion within the next twenty-four months and represents the sole recompete exposure in that window. The vendor's capability framing aligns with NAICS 334516 (Analytical Laboratory Instrument Manufacturing), which covers 53 of the 76 awards; 7 additional awards fall under merchant wholesale of professional equipment, and 4 under equipment repair and maintenance services. All contract work is firm fixed-price purchase order activity; SCI-reportable invoiced activity in the source dataset totals $128 thousand across one record in FY2023. The vendor does not subcontract and operates with no named subcontractor relationships in the federal record, meaning all work is performed by TSE Systems internal delivery teams.
