CDC/NIOSH sole source procurement of Phenom Pharos G2 desktop field emission SEM with EDS detector

The National Institute for Occupational Safety and Health (NIOSH), Respiratory Health Division, part of the Centers for Disease Control and Prevention (CDC), is seeking to procure a specialized desktop scanning electron microscope (SEM). - Government Buyer: - Centers for Disease Control and Prevention (CDC) - National Institute for Occupational Safety and Health (NIOSH) - Respiratory Health Division - OEM and Vendor: - Nanoscience Instruments, Inc. (sole source vendor) - Product Requested: - Phenom Pharos G2 desktop field emission scanning electron microscope (FE-SEM) - Includes energy dispersive x-ray spectroscopy (EDS) detector for elemental mapping - Quantity: 1 unit - Designed for high magnification and resolution, capable of imaging particles as small as a few nanometers - Unique Requirements: - Must have a field emission electron beam source - Must include an EDS detector for elemental mapping - Only the Phenom Pharos G2 model meets these technical specifications - Sole source justification due to lack of alternative sources meeting the requirements

Description

The Centers for Disease Control and Prevention intends to award a sole source firm fixed price purchase order to Nanoscience Instruments for purchase of Phenom Pharos G2 desktop model scanning electron microscope (SEM) with field emission electron beam source and an energy dispersive x-ray spectroscopy (EDS) detector capable of elemental mapping. There are two types of beams, field emission and tungsten filament. Traditional tungsten filaments are limited to approximately 250,000x magnification whereas a field emission source can achieve up to 8 times greater resolution (up to 2,000,000x magnification), which permits imaging particles with sizes of just a few nanometers. As such, the 2 key requirements for this procurement are a field emission electron beam source and elemental mapping capability. Only the Phenom Pharos G2 desktop scanning electron microscope (SEM) with field emission electron beam source and an energy dispersive x-ray spectroscopy (EDS) detector capable of elemental mapping sold by Nanoscience Instruments, Inc. meets both these requirements.

This contract action is for supplies and/or services for which the Government intends to solicit and negotiate with only one source under the authority of FAR 13.101(b) (SAP). 

This notice of intent is not a request for competitive quotations; however, all quotations/responses received within fifteen (15) days of the issuance of this notice shall be considered by the government.  A determination by the government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the government.  Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement.  Any quotation/response should be emailed to Marie Claxton at email utj4@cdc.gov by 11:00am EST on Sept 1, 2026.
