About the company
Sheldon Manufacturing, Inc. (doing business as Sheldon Manufacturing Inc. and Shel Lab) manufactures and delivers specialized laboratory equipment — thermal vacuum chambers, laboratory ovens, turbopumps, incubators, and anaerobic chambers — to federal agencies primarily as a small business prime contractor under Total Small Business set-asides, with one recent subcontract to Astrion Group, LLC.
Sheldon Manufacturing is a for-profit corporate entity headquartered in Cornelius, Oregon. The vendor's capability footprint centers on industrial process furnaces and ovens (NAICS 333994), analytical laboratory instruments (NAICS 333515 derived), and surgical appliance manufacturing, with primary PSC alignment to Laboratory Equipment and Supplies (PSC 6695 and related codes) and Medical and Surgical Instruments, Equipment, and Supplies. Recent representative work includes a $137,923 Total Small Business purchase order from NASA's Shared Services Center awarded September 9, 2026, for a custom SVO-10-T thermal vacuum oven with ultra-high vacuum viewing window rated below 2E-6 Torr, a $26,000 sole-source delivery of a spare Hipace700 turbopump to NASA Langley Research Center for existing Cascade TEK SVO-10 thermal testing assets (December 2, 2025), and a $20,233 Total Small Business award from the Indian Health Service for laboratory-grade incubators delivered to Shiprock, New Mexico (July 12, 2023).
Customer concentration is highly dispersed across 26 distinct federal agencies. NASA Shared Services Center anchors the potential-value ranking with two awards worth $164 thousand combined, while the Department of State, Department of Veterans Affairs Veterans Integrated Service Network 17, Department of the Army Medical Command, and Department of Health and Human Services Food and Drug Administration round out the top five by potential value (covering 57% of combined potential value). The Army Medical Command leads by award count with five awards, but the portfolio shows no dominant customer relationship — the top five agencies account for only 23% of all awards. The source data indicates 57 total awards across the vendor's lifetime; recent activity (2023–2026) shows only three awards in 2026, two in 2025, and two in 2023, suggesting activity is episodic and small-order driven. One award (the September 2026 NASA Shared Services Center thermal vacuum chamber) reaches ultimate completion in the next twenty-four months, with combined recompete exposure of $138 thousand. The vendor holds no seat on government-wide acquisition contracts or standing BPAs; work is transacted via individual purchase orders. In its single subcontractor role, Sheldon Manufacturing supplied equipment under Astrion Group, LLC on the Laboratory Support Services and Operations II (LASSO) II Contract (May 11, 2026).
