Optical Particle Counters

The National Institute of Standards and Technology (NIST) is seeking to procure optical particle counters through solicitation NB647070-25-02130 to support breathalyzer development research for detecting drug molecules like tetrahydrocannabinol (THC). The procurement requires benchtop instruments with diode lasers capable of measuring particle sizes between 0.3-10 micrometers and providing particle counts in at least 16 size bins, with built-in pumps delivering minimum 1 L/min sample flow and ISO 21501 calibration certification. Vendors must demonstrate technical capability to measure sub-micrometer breath aerosol particles at extremely low concentrations and provide software with data export capabilities along with comprehensive documentation. The solicitation will be evaluated using Lowest Price Technically Acceptable (LPTA) criteria under FAR Part 13 Simplified Acquisition Procedures, with technical capability assessed on an acceptable/unacceptable basis. Quotations must be submitted electronically to lisa.stevens@nist.gov by July 21, 2025, with delivery required within 8 weeks after receipt of order according to the RFQ document, though the Statement of Work specifies 3 months delivery timeframe.

This procurement operates under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) with no set-aside designation, making it available to all qualified vendors including large businesses. The solicitation contains conflicting quantity information, with the RFQ specifying 1 optical particle counter while the Statement of Work indicates a requirement for 2 units. Performance will take place at NIST's Boulder, Colorado facility at 80305, with FOB Destination shipping terms requiring the contractor to handle delivery logistics. The contract includes a one-year warranty covering all parts, labor, and shipping, with Net 30 payment terms and no installation or training services required. No incumbent contractors or budget ranges are specified in the available documentation, and vendors must provide country of origin information for instruments manufactured outside the United States.
