Sonic Nozzle Gas Mixing Instruments

The National Institute of Standards and Technology (NIST), a civilian agency within the Department of Commerce, is seeking quotations for Sonic Nozzle Gas Mixing Instruments to support the Chemical Science Division's research into optical impurity analysis of semiconductor gases under the CHIPS Metrology Program. The instruments must feature sonic nozzles with 1,024 source gas dilution points, achieve relative uncertainty in dilution of less than 1 percent, provide relative stability of less than 0.5 percent, and support adjustable outlet flow rates up to 5 L/min with compatibility for air and nitrogen dilution gases. All equipment must be new, shipped in original manufacturer packaging with complete documentation, and include USB communication capability and compatibility with standard 19-inch instrument racks. Award will be made to the lowest-priced, technically acceptable offeror, with technical acceptability evaluated first based on demonstrated compliance through citations, product literature, technical descriptions, or charts rather than simple assertions of compliance. Quotations must be submitted electronically in three separate volumes—Technical Quotation, Price Quotation, and Terms and Conditions—to junee.johnson@nist.gov and forest.crumpler@nist.gov by 12:00 PM Eastern Time on February 17, 2026, with pre-quote inquiries due no later than February 5, 2026.

This is a Total Small Business set-aside under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) with a 1,000-employee size standard, with no identified incumbent contractors. The procurement includes three Sonic Nozzle Gas Mixing Instruments, two units with Silconert coating, two additional Silconert-coated inlets, one portable carrying case, and comprehensive installation, startup, and training services at NIST's Gaithersburg, Maryland facility. All items except installation and training must be delivered within 10 weeks of award, with installation and training to be completed within 14 weeks; payment is 100 percent upon installation, acceptance, and successful performance demonstration with a one-year warranty commencing upon government acceptance. Quotations must include firm-fixed pricing with all shipping costs and applicable tariffs on an FOB Destination basis and remain valid for 90 days. The place of performance is Gaithersburg, Maryland, and the specific equipment requirements, such as 1/4-inch metal gasket face seal (VCR) fittings and outlet pressure capability up to 100 kPa, must be met by all proposed instruments.
