The National Institutes of Health's National Institute of Arthritis and Musculoskeletal and Skin Diseases intends to award a sole-source, firm-fixed-price purchase order to BD Biosciences for a BD FACSymphony A5 Flow Cytometer service agreement covering a base year and two option years. Required services include remedial repairs, two preventive maintenance inspections annually, unlimited telephone technical support, and on-site service within 48 hours when telephone support is unsuccessful. This is an active procurement notice of intent, not a grant program, with responses due November 13, 2026.
