About this opportunity
The Food and Drug Administration seeks quotation for a Sodium Iodide Detector for Thyroid Counting system, with proposals due August 31. The procurement is a Total Small Business set-aside under NAICS 334516 (Analytical Laboratory Instrument Manufacturing), with a 1,000-employee size standard.
Place of performance is Winchester, Massachusetts at the FDA Winchester Engineering and Analytical Center (WEAC). The requirement supports thyroid counting capability mandated under NRC License No. 20-08361-01 and serves as a safety resource for multiple FDA offices.
The solicitation requests two deliverables by September 15: a 3"×3" NaI(Tl) LED stabilized scintillation detector with energy range 30 keV to 3 MeV, resolution exceeding 7%, operating temperature −20 to +50 degrees Celsius, operating humidity up to 85% non-condensing, diameter less than 3.5", and weight under 6 pounds; and a digital tube-based multichannel analyzer with 14-bit ADC, 20 MHz sampling, software-programmable gain (coarse and fine), and integrated HVPS and preamplifier. Equipment must be seamlessly compatible with Apex InVivo Software and Mirion Osprey Multichannel Digital Analyzer. The estimated award value is $20,000. The contract type is Firm-Fixed-Price Purchase Order. The contractor furnishes all shipping, handling, and freight costs to the WEAC facility during normal business hours (Monday–Friday, 8:00 AM–4:00 PM). A minimum 12-calendar-month warranty covering parts and labor is required, beginning upon formal Government acceptance. Payment terms are Net 30 following Government acceptance via Treasury's Invoice Processing Platform. Award will be made to the lowest-priced technically acceptable responsible offeror.
