Two 2.3K Mechanical Cryocooler Systems

The Quantum Nanophotonics group requires two 2.3K Mechanical Cryocooler Systems, each with a compressor, hoses, and cold head. These systems will cool electronics and optics to 2.3K, fitting into existing cryostats designed for Sumitomo RDK-101DL or equivalent. Each cryocooler must reach 2.3K or colder, with 0.1W or more cooling power at 4.2K. The units require a small, 120VAC-powered, air-cooled compressor with approximately 10-foot helium lines. The cold head must match the Sumitomo RDK-101DL's size and dimensions. Phased delivery is acceptable, with each system delivered as a complete unit. Government acceptance may exceed seven days, but no specific requirements for installation, warranty, training, maintenance, repair, or government-furnished materials are listed.

This federal solicitation specification document details the requirements for the procurement of two complete 2.3K mechanical cryocooler systems. Issued by the Physical Measurement Laboratory (PML), Applied Physics Division, Quantum Nanophotonics Group within the National Institute of Standards and Technology (NIST), the equipment will be integrated into existing, NIST-assembled cryostats designed to accommodate a Sumitomo RDK-101DL cryocooler or its dimensional equivalent. Each system must include a cold head, an air-cooled compressor operating on 120VAC power, and flexible helium lines between 6 and 15 feet in length. Performance specifications require a base temperature of 2.3K or lower and a minimum cooling power of 0.1W at 4.2K. Key administrative and delivery terms include: - Shipping: Partial delivery is acceptable, with final delivery of all goods, installation, and training required no later than 20 weeks after receipt of order (ARO). - Inspection and Acceptance: A 21-business-day government acceptance period is established, which includes up to two weeks for system installation prior to formal inspection. - Warranty: A standard base manufacturer warranty is required. No additional facility modifications, specialized on-site training, maintenance plans, or travel are requested under this specification.

This document is a combined synopsis/solicitation issued by the National Institute of Standards and Technology (NIST) for a commercial item procurement under solicitation number NB686100-26-01895. Conducted as an unrestricted, open-market acquisition under Simplified Acquisition Procedures (FAR 13), the government is seeking firm-fixed-price quotations for two mechanical cooler systems to 4K, which must include compressors, cold heads, and flexible helium lines. The evaluation will be conducted using the Lowest Price Technically Acceptable (LPTA) source selection process. Quotations will be evaluated based on two factors: Technical Capability (rated on an acceptable/unacceptable basis) and Price. To be considered for award, offerors must submit detailed technical descriptions, product literature, or drawings demonstrating conformity with the specifications, rather than simply copying the requirements. Deliveries are required within 20 weeks after receipt of order (ARO) to the NIST campus in Boulder, Colorado, on an FOB Destination basis. Offerors must maintain an active registration in the System for Award Management (SAM) under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing). Quotations, including separate technical and price proposals, must be submitted electronically to Contract Specialist Deionne Jones at deionne.jones@nist.gov by the specified closing date and time.
