About the company
Cole-Parmer Instrument Co LLC, doing business as Zefon International, manufactures industrial hygiene and workplace safety equipment including respirable dust cassettes, air sampling consumables, gravimetric filters, dust pumps, cyclone assemblies, and related technical support services, operating as a prime contractor on full-and-open federal procurements with no set-aside designations. The Ocala, Florida-based company is a subsidiary of Cole-Parmer Instrument Company, LLC, and competes entirely as a prime (100% of recent awards), with no subcontract footprint.
Customer concentration is extreme: the Department of Labor Mine Safety and Health Administration accounts for 32 awards and $33.1 million in combined potential value — 97.6% of the vendor's $33.9 million combined portfolio. The Department of Labor Occupational Safety and Health Administration represents the second customer with six awards and $500 thousand in potential value; all other federal customers combined account for less than 2% of the portfolio. MSHA's work centers on air sampling consumables and exposure monitoring equipment supporting the agency's mine worker safety mission.
Zefon International holds position on five named parent vehicles, with the highest concentration on a single-award Blanket Purchase Agreement 1605C4-25-A-0001 established with MSHA on October 30, 2024, carrying a $4.2 million ceiling through October 29, 2026. That vehicle has generated five task orders (combined potential value $4.2 million) issued between October 2024 and August 2026 for respirable dust cassettes, air sampling equipment, and Cole-Parmer products. The vendor also places work under three additional MSHA indefinite delivery contracts (DOLMSH15D0013, DOLMSH15D0020, and DOLMSH15D0021) totaling 23 task orders and $5.3 million in combined potential value, and sits on OSHA's IDIQ 1605C1-21-D-0001 with three delivery orders valued at $137 thousand for gravimetric filters and technical support.
Award activity has declined from a peak of six awards in 2022 to one in 2025 and three in 2026; two awards with combined potential value $1.1 million are reaching ultimate completion within the next twenty-four months, placing modest recompete exposure. Recent representative work includes a $1.3 million BPA call from MSHA issued December 12, 2025, for Cole-Parmer products (ultimate completion January 2026); an $859 thousand BPA call from MSHA issued August 10, 2026, for Cole-Parmer products (ultimate completion September 2026); and a $672 thousand BPA call from MSHA issued August 13, 2026, for Cole-Parmer products (ultimate completion September 2026). The vendor's NAICS profile centers on Analytical Laboratory Instrument Manufacturing (17 awards), Other Measuring and Controlling Device Manufacturing (13 awards), and Instruments for Industrial Process Variables (12 awards), with primary PSC coding in Laboratory Equipment and Supplies (14 awards) and Miscellaneous Special Industry Machinery (12 awards).
