SOLE SOURCE REQUEST TO PURCHASE WRK String Spectrometer Instrument and WRK Flight-line Sample Collector System with corresponding parts kits, weather & speed kit, and all associated components.

Mississippi State University is seeking sole-source procurement of the WRK String Spectrometer Instrument and WRK Flight-line Sample Collector System, along with associated parts kits, weather and speed kits, and all components, to support aerial spray research using unmanned aerial systems. The equipment is uniquely designed and hand-built by WRK of Oklahoma under Dr. Richard Whitney, who is the only entity capable of providing this specific technology, as no commercial alternatives exist that can measure effective swath width, droplet spectrum, percent coverage, and deposition uniformity with the same precision. The procurement is justified under FAR 6.302-1 due to the instrument’s proprietary design, lack of market alternatives, and prior successful use in peer-reviewed research and training clinics conducted by the university. The total estimated cost is $25,695 plus shipping, with no formal line-item pricing, contract clauses, or FAR/DFARS provisions included, as this is a justification rather than a competitive solicitation. Delivery is required to 245 Barr Avenue, Room 610, Mississippi State, MS, and the response deadline is July 22, 2026. No evaluation factors, inspection criteria, packaging standards, or acceptance protocols are specified, as the acquisition relies entirely on the uniqueness of the product and the absence of competitive options. The university bears the burden of proof to demonstrate exclusivity, and any objections must be submitted in writing to the Chief Procurement Officer with supporting evidence. The vendor, WRK of Oklahoma, has no formal government identifiers listed, and no socioeconomic certifications, representations, or certifications are provided. Payment and invoicing methods are unstated, and no contracting officer representative or technical representative is named, with primary contact for procurement inquiries directed to Debra Raines and Jennifer Mayfield. The procurement is non-defense, research-focused, and involves no security clearances or organizational conflict of interest safeguards.
