TSS Microscopy, LLC

TSS Microscopy, LLC, a self-certified small disadvantaged business limited liability company headquartered in Hillsboro, Oregon, repairs, maintains, and supports electron microscope equipment for federal research, defense, and materials-testing laboratories as a prime contractor. The vendor operates exclusively on full-and-open purchase orders; no set-aside designations appear in the recent award record except for one Total Small Business set-aside.

TSS Microscopy's capability portfolio centers on field service and repair for sophisticated electron microscopy platforms — FEI Helios FIB/SEM dual-beam systems, Thermo Fisher FEI Tecnai transmission electron microscopes, TESCAN VEGA scanning electron microscopes, and Philips transmission electron microscopes. Representative work includes a $109,500 firm fixed-price purchase order from the Army's Materiel Command (Research Development and Engineering Command) awarded May 12, 2026, for annual maintenance, preventive maintenance visits, calibration, original equipment manufacturer parts replacement, and software updates to an FEI Helios 600i system at Benet Laboratories, Watervliet Arsenal, New York, running through March 31, 2027; a $24,365 repair and maintenance purchase order from the Department of Agriculture's Agricultural Research Service for restoration of a Thermo Fisher FEI Tecnai 12 transmission electron microscope at the Albany, California Bioproduct Research Unit (awarded October 30, 2024, extended through April 30, 2025); and a $43,200 Total Small Business set-aside for decommissioning a Philips transmission electron microscope at NIST's Gaithersburg campus (awarded May 24, 2022).

Customer concentration is highly distributed across five distinct agencies with no customer anchoring more than one award. The Department of the Navy Naval Education and Training Command and the Department of the Army Materiel Command each account for one award but together represent $231,000 of the $308,000 combined potential value. Activity is episodic — five awards across the 2019–2026 period with no recurring pattern — and only one award (the Army maintenance contract for $110,000) faces ultimate completion within the next twenty-four months, creating a single recompete opportunity. The vendor has no subcontract footprint and no parent vehicles or IDVs in the source data. Combined dollars obligated across all awards total $293,000, representing 95 percent of combined potential value.
