Sterlitech Corporation

Sterlitech Corporation, doing business as Sterlitech Corp, manufactures and sells specialized laboratory filtration equipment—membrane filters, reverse osmosis elements, and tangential flow kits—to federal agencies as a prime contractor (96% of recent awards) competing predominantly full-and-open without set-aside designation. The Auburn, Washington-based for-profit Subchapter S corporation operates as a manufacturer of goods holding a $500 thousand General Services Administration Multiple Award Schedule contract that anchors most of its federal ordering activity.

Sterlitech's customer concentration is extreme and narrow. The Mine Safety and Health Administration accounts for nine awards worth $442 thousand combined potential value—63% of all awards by count and 31% of total potential value—driven by recurring delivery orders for silver membrane filters supporting MSHA's silica analysis laboratory. Two recently awarded single-award BPAs with MSHA (one for $130.9 thousand through May 2029, another for $148.5 thousand through March 2029) extend this relationship and will drive near-term volume. The Department of the Interior Bureau of Reclamation, the Department of the Navy Naval Sea Systems Command, the Department of the Army Materiel Command, and the Department of Agriculture Agricultural Research Service round out the active customer set, each accounting for one to three small-dollar awards. The GSA Federal Acquisition Service appears in the potential-value ranking ($500 thousand) as the holder of Sterlitech's MAS vehicle itself, not as a customer placing task orders. Sterlitech's top five customer agencies (by count and by value) account for 63% of awards and 88% of combined potential value, reflecting extreme concentration risk in a single agency's need for one commodity class.

Sterlitech places work under the GSA Multiple Award Schedule (5 task orders, $119 thousand combined potential value) and two MSHA single-award Blanket Purchase Agreements (2 task orders, $44 thousand combined potential value). Representative prime work includes a May 2026 BPA call from MSHA for silver membrane filters (ceiling $26.2 thousand, completion May 2027), a June 2025 purchase order from Naval Sea Systems Command for FilmTec reverse osmosis membrane elements (ceiling $22.7 thousand, total small business set-aside), a September 2025 purchase order from the Bureau of Reclamation for a TSC IRA 8190 Membrane Test Skid (ceiling $144.6 thousand, total small business set-aside), and a May 2024 purchase order from West Point Military Academy for tangential flow kits (ceiling $25.9 thousand). Award size ranges from $17 thousand to $148.5 thousand, with a combined potential value of $1.4 million across all 27 recent awards. Activity has grown modestly from one award per year in 2022–2023 to four awards per year in 2025–2026. Only one award (combined potential value $26 thousand) faces completion and recompete inside the next twenty-four months. Sterlitech subcontracts to HII Mission Technologies Corp on Department of Navy research, development, test, and evaluation work for in-service engineering agent capabilities, accounting for the single sub-award in the recent portfolio. Primary NAICS coding centers on Analytical Laboratory Instrument Manufacturing (13 awards) and Surgical Appliance and Supplies Manufacturing (6 awards), with Laboratory Equipment and Supplies as the dominant PSC category (17 awards).
