NIH/NINDS intends to award a sole-source firm-fixed-price purchase order to BD Biosciences for a base-plus-two-option-year service agreement on the BD FACSymphony A-5 Flow Cytometer (Serial No. R66096400071), citing BD as the OEM and sole source. The agreement requires two preventive maintenance inspections per 12-month period, unlimited telephone technical support, on-site service within 48 hours if support is unsuccessful, OEM-certified parts and technicians, and remedial repairs at no additional cost to the Government. Services must be performed 8:00 AM–5:00 PM Bethesda, MD local prevailing time Monday–Friday, with emergency support as needed excluding Federal holidays. The Government anticipates making an award approximately five calendar days after the notice closes unless another responsible source is found capable of meeting the requirement. Interested parties may submit a capability statement electronically for review, though this is not a request for competitive quotations or proposals.
