Spectrofluorometer (Fluorimeter) System Replacement

Summary (Newest Update)

Background The USAF Academy (USAFA), Department of Chemistry is seeking to replace a 20+-year-old fluorimeter that is no longer operational due to the unavailability of replacement parts. This modern replacement is essential for sustaining upper-division course instruction, which impacts 60 to 80 cadets annually. The solicitation is a Request for Information (RFI) aimed at identifying capable sources and evaluating potential small business set-aside opportunities for a high-performance spectrofluorometer system. Work Details The contract requires the delivery of a commercial spectrofluorometer system that meets or exceeds the following specifications: - **Multiple Data Collection Modes**: Capable of fluorescence, phosphorescence, chemi-luminescence, and bio-luminescence. - **Excitation Source**: Must utilize a Xenon flash lamp-based system with high-frequency flash rates to minimize fluorescence photo-bleaching and provide room-light immunity. - **Optical Beam Geometry**: Configured to maximize collection efficiency with low sample volumes in cuvettes. - **Sensitivity & Detection**: Equipped with a high-sensitivity photomultiplier tube for enhanced sensitivity above 700 nm, capable of measuring picomolar amounts of fluorescein. - **Signal-to-Noise Ratio (SNR)**: Guaranteed SNR of >500:1 for the Raman Band of Water using excitation at 500 nm and a 1-second signal averaging time. - **Sample Handling & Temperature Control**: Must measure four or more cells automatically, include a solid sample holder accessory kit for various sample types, and provide a water-thermostatted single-cell holder with a compatible water pump (110V with standard US plug). Period of Performance The geographic location(s) the product will be delivered to or performed at. Place of Performance USAF Academy, Colorado. Bidder Requirements Bidders must demonstrate capability in providing the specified spectrofluorometer system and may need to show compliance with any relevant manufacturer or reseller authorizations.
