BACKGROUND The National Institute of Standards and Technology (NIST) The Fundamental Thermodynamics Group (685.09) conducts fundamental and applied research to improve the measurement of thermodynamic quantities. Develops new measurement methods for pressure, vacuum, and temperature using atomic and molecular gases, refractometry, solid-state point defects, optomechanics, integrated photonics, advanced nanofabrication technologies, and advanced AI. The group continuously improves the performance of national standards, participates in national and international intercomparisons to validate these standards, and produces assessments of their respective measurement uncertainty. To expand NIST’s calibration capabilities and continue delivering for NIST’s vacuum calibration customers, we need to acquire a high-frequency SRG. The high-frequency design is both less susceptible to mechanical vibration instabilities and suffers lower systematic uncertainty due to sensor orientation. Acquiring one of these new high-frequency SRGs is critical to our ability to continue to deliver calibrations to all potential customers with the lowest possible uncertainty. NIST is seeking information from sources that may be capable of providing a solution that will achieve the objectives described above, in addition to the following essential requirements Contract Line-Item Number (CLIN) 0001: The Contractor shall provide one (1) high-frequency spinning rotor gauge The system shall meet or exceed the technical specifications identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. High-frequency spinning rotor gauge That can achieve pressure measurement accuracy of +/- 1 % or better. That has a long-term accuracy drift less than 1 % per year. That has a measurement range of at least 10 mbar to 5x10-7 mbar. Has an operation temperature range of at least 10 °C to 40 °C. Is programmable using included Labview drivers. Is operable with an included computer graphical user interface. Is manufactured by Ph Instruments. And consisting of: A sensor tube assembly with A DN40CF vacuum flange. A stainless steel sensor ball with a nominal diameter of 4.5 mm. A screw mechanism to attach a measurement head (see A.8 below). A measurement head that Can produce a magnetic levitation field of at least 90 mT. Can accelerate the sensor ball to rotation speeds of at least 615 Hz. Connects to the electronics unit (see A.9 below) via a cable at least 3 m long. Produces reliable pressure readings when horizontally aligned to within +/- 2°. An electronics unit that Is powered using 24 V DC, <= 1 A. Communicates with a computer with USB, RS232, and RS485 via USB-C and HD Sub-D 15 pin connectors. Can use ModBus and ASCII protocols for computer communication. Has a 0 V to 10 V analog output. NIST conducted market research from October 2024 – April 2025 by, speaking with colleagues, performing internet searches, and speaking with vendors to determine what sources could meet NIST’s minimum requirements. The results of that market research revealed that only Daventria, LLC (D5RDA2G453D5) can meet all the Governments minimum requirements. HOW TO RESPOND TO THIS NOTICE In responding to this notice, please DO NOT PROVIDE PROPRIETARY INFORMATION. Please include only the following information, readable in either Microsoft Word 365, Microsoft Excel 365, or .pdf format, in the response: Submit the response by email to the Primary Point of Contact and, if specified, to the Secondary Point of Contact listed in this notice as soon as possible, and preferably before the closing date and time of this notice. Please note that to be considered for award under any official solicitation, the entity must be registered and “active” in SAM at the time of solicitation response. Provide the complete name of your company, address, name of contact for follow-up questions, their email, their phone number and, if your company has an active registration in https://sam.gov, your company’s Unique Entity ID (UEI). Details about what your company is capable of providing that meets or exceeds NIST’s minimum requirements. Whether your company is an authorized reseller of the product or service being cited and evidence of such authorization. Identify any aspects of the description of the requirements in the BACKGROUND section above that could be viewed as unduly restrictive or create unnecessary barriers that adversely affect your firm’s ability to fully participate in a procurement for such services and explain why. Please offer suggestions for how the requirements could be organized or structured to encourage the participation of small businesses. For the NAICS code Indicate whether your company is (a) a small business or (b) other than small business. See the Table of Small Business Size Standards and the associated .pdf download file for small business size standards and additional information. If you believe the NAICS code listed in this notice is not the best NAICS code for the type of product addressed in this notice, identify an alternative NAICS code that you believe would be more appropriate for the planned procurement. If your firm has existing Federal Supply Schedule contract(s) or other contracts for products or services against which the Department may be able to place orders, identify the contract number(s) and other relevant information. Describe your firm’s experience (as a prime, subcontractor, or consultant) providing the products or services described in Background section. Provide any other information that you believe would be valuable for the Government to know as part of its market research for this requirement. Please let us know if you would like to engage to get a better understanding of the requirement or need additional information about the Government’s requirement for the products or services described in the Background section. QUESTIONS REGARDING THIS NOTICE Questions regarding this notice may be submitted via email to the Primary Point of Contact and the Secondary Point of Contact listed in this notice. Questions should be submitted so that they are received within 3 days of this notice , 2025. If the Contracting Officer determines that providing a written amendment to this notice to document question(s) received would benefit other potential respondents, the questions would be anonymized, and a written response to such question(s) would be provided via an amendment to this notice. IMPORTANT NOTES The information received in response to this notice will be reviewed and considered so that the NIST may appropriately solicit for its requirements in the near future.
