The Department of Health and Human Services, specifically the Food and Drug Administration (FDA), is seeking sources for Solid Phase Extraction HLB Cartridges, 60 mg, 3 mL with DEC Caps for its Arkansas Human and Animal Food Laboratory. The FDA requires 7,000 cartridges that are validated for use on regulatory samples, specifically for analyzing chloramphenicol and nitrofurans in aquaculture species, utilizing the Gilson GX-274 automated solid phase extraction system. These cartridges are critical for the laboratory's routine analysis of over 6,000 subsamples annually, supporting the FDA’s antibiotics in aquaculture program. Interested vendors, particularly small businesses under NAICS Code 334516, must submit capability statements, including business overviews and past performance, by August 17, 2025, to David Kramer at david.kramer@fda.hhs.gov.
