AI Contract Overview
The Food and Drug Administration is seeking quotations for a firm-fixed-price purchase order under solicitation 75F40126Q00375. The contract involves the procurement of a 3x3 LED temperature stabilized Sodium Iodide probe and a digital tube based multichannel analyzer with USB and Ethernet output. Both components must be seamlessly compatible with Apex InVivo Software and the Mirion Osprey Multichannel Digital Analyzer. The estimated value of the contract is 20,000 dollars, with a required delivery date of September 15, 2026. The equipment must meet strict technical specifications, including an energy range of 30 keV to 3 MeV for the detector and a 14-bit 20 MHz sampling ADC for the analyzer. The detector must weigh less than 6 lbs and have a diameter under 3.5 inches. The contractor is required to provide a minimum 12-month warranty covering all parts and labor starting from the date of government acceptance. This opportunity is designated as a total set-aside for small businesses.
