This is a sole-source, firm-fixed-price commercial contract for a replacement Type II laboratory water purification system (Milli-Q® HX 7040) to interface with legacy infrastructure in Building 362, with an estimated value of approximately $45,500. The associated deliverables include on-site system startup, loop sanitization, and a booster pump. The sole-source justification is based on EMD Millipore being the only provider able to meet physical and operational interface requirements with existing plumbing, storage tanks, and laboratory loops without redesign or costly facility modifications. The contracting activity intends to award directly to EMD Millipore Corporation, but any responsible source that believes it can meet the requirements may submit a capability statement demonstrating how an alternate system can interface with the legacy configurations without modification. This is not a competitive request for proposals.
