Plexon, Inc.

Plexon, Inc., a Dallas, Texas-based for-profit manufacturer of neuroscience research equipment and neural data acquisition systems, operates as a prime contractor supplying specialized scientific instruments to federal research agencies. The company competes exclusively in full-and-open competition with no set-aside designation across its federal portfolio; all 189 recent awards are prime purchases, with zero subcontract engagement.

Plexon's customer footprint concentrates tightly within the Department of Health and Human Services, specifically the National Institutes of Health and its institutes. The top five customer organizations account for 67% of awards by count and 66% by potential value. The National Institute on Drug Abuse leads both rankings with 70 awards valued at $2.7 million combined potential value, followed by the NIH Office of Logistics and Acquisition Operations (24 awards, $1.9 million), the National Eye Institute (13 awards, $1.1 million), the National Institute of Environmental Health Sciences (9 awards, $491 thousand), and the NIH Office of the Director (11 awards, $248 thousand). The vendor also holds a single award from the Department of Veterans Affairs (VISN 23).

Plexon's capability portfolio centers on multi-channel electrode arrays, neural data acquisition systems (including its proprietary Omniplex and SINAPS systems), optogenetic stimulation equipment, photometry systems, custom headstages, and related electrophysiology instrumentation. Representative recent work includes a $690,800 firm fixed-price purchase order from the National Eye Institute (July 2024) for four identical Omniplex data acquisition systems to support neuronal recordings at the Briggs LSR Lab; a $158,565 purchase from the NIH Office of Logistics and Acquisition Operations (April 2025) for lab supplies supporting ongoing research experiments; a $70,650 National Eye Institute purchase order (June 2026) for SINAPS Omniplex Bundle A components including a 4-port HDP, SINAPS adaptor, HDMI cable, and SINAPS and OPX licenses; and a $87,265 National Eye Institute order (June 2025) for neural data acquisition systems, multi-channel electrodes, and photometry equipment.

Activity has remained modestly stable year over year (six awards in 2022, seven in 2023, five in 2024, six in 2025, one in 2026), with combined obligated dollars of $9.6 million across the portfolio. Only one award faces ultimate completion inside the next twenty-four months ($71 thousand combined potential value), presenting minimal near-term recompete exposure. The vendor's NAICS concentration clusters in All Other Professional, Scientific, and Technical Services (77 awards) and Analytical Laboratory Instrument Manufacturing (46 awards); PSC concentration aligns to Laboratory Equipment and Supplies (128 awards) and Medical and Surgical Instruments, Equipment, and Supplies (16 awards). Plexon has maintained federal vendor registration since 2002 and operates under a single identified blanket purchase agreement (MD210396) with one task order.
