The University of Mississippi is issuing a sole-source notice for a refurbished Beckman LS6500 Liquid Scintillation Counter, with objections due June 29, 2026 at 10:00 a.m. Central Time. GMI OpCo, LLC is identified as the only qualified vendor; the University will proceed with competitive bidding if alternative sources are identified through the objection period, or will appeal to the Public Procurement Review Board for approval if none emerge.

The Department of Chemistry & Biochemistry requires this equipment to support research activities involving detection and quantification of low-level radioactive isotopes in biological and chemical samples. The LS6500 provides the sensitivity, counting efficiency, and analytical capabilities required for existing research protocols. Beckman Coulter no longer manufactures or supports the LS6500. GMI OpCo, LLC holds the sole qualification to supply a re-certified instrument and manage all regulatory transfer requirements for equipment containing a radioactive source.

The total cost is $20,994.36. The University determined this price reasonable given the discontinued status of the equipment and engaged the supplier to obtain educational discounts. Objections must be submitted to Jeff Wells, Procurement Manager, University of Mississippi Procurement Services, by hand delivery, regular mail, overnight delivery, or email to solesource@olemiss.edu with a copy to purchase@olemiss.edu.
