Dual Channel Modular Pressure Controllers

The National Institute of Standards and Technology (NIST) has issued a solicitation for two high precision dual channel modular pressure controllers to support the Chemical Sciences Division's Direct Air Capture (DAC) research program. The procurement requires specialized instruments capable of controlling absolute pressures from 0.3 to 1.5 bar across two independent channels, with exceptional accuracy (0.008%), precision (0.004%), and stability (0.003%) specifications for use with clean nonflammable gases. Each unit must be a benchtop instrument with modular transducer units, 15-second control speed, temperature compensation between 15-45°C, RS-232 communication protocol, and U.S. electrical compatibility (60 Hz, 110V). The solicitation will be evaluated using the Lowest Price Technically Acceptable (LPTA) method under Simplified Acquisition Procedures, and quotations must be submitted electronically to contract specialist de Ionne Jones by the closing date of July 28, 2025.

This procurement is unrestricted with no set-aside designation and falls under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing), which has a small business size standard of 1,000 employees. The solicitation documents indicate a discrepancy in delivery requirements, with the Statement of Work specifying 61 days after award while the RFQ states sixteen weeks after receipt of order. The instruments will be delivered FOB Destination to NIST facilities, with the RFQ indicating Boulder, CO as the delivery location and the Statement of Work referencing Gaithersburg, MD for shipping and receiving, with the place of performance listed as Potomac, MD. Each unit must include comprehensive documentation, a minimum one-year warranty covering parts and labor, technical support services, and will undergo a two-week acceptance period for performance verification by NIST's technical expert following delivery.
