Rotational Rheometer System

The Food and Drug Administration's Center for Drug Evaluation and Research seeks one complete turn-key Rotational Rheometer System, a newly manufactured latest-model instrument to support advanced bioprocessing research and development, with quotes due June 12, 2026, at 1:00 PM Central Time. The procurement is unrestricted and open to all qualified vendors; award will be made on a firm-fixed-price basis to the lowest price technically acceptable and responsible offeror.

Place of performance is the FDA's Silver Spring, Maryland facility at 10903 New Hampshire Avenue, with FOB destination delivery. All shipping, handling, delivery, installation, and training charges must be included in the quoted price. The system must feature a frictionless brushless DC servo air bearing motor with specified oscillation amplitude and frequency ranges, high-precision torque/force rebalance transducers, stepper motor encoder systems for gap travel measurement, Peltier-controlled temperature capability from minus 10 to 150 degrees Celsius, Forced Convection Oven from minus 150 to 600 degrees Celsius, and support for steady shear, oscillatory rheological, transient, non-linear, and extensional viscosity measurements. High-speed data acquisition of at least 15,000 Hz for oscillatory measurements, advanced axial force control, wireless temperature sensors, integrated software with advanced rheological modeling and data analysis tools, and interchangeable geometries (parallel plate, cone-and-plate, concentric cylinder) are required. The system must include Installation Qualification and Operational Qualification documentation, on-site training, and a minimum one-year comprehensive warranty covering all parts and labor. Quotes must remain firm through September 30, 2026. Payment terms are Net 30 days following government acceptance, with electronic invoicing through the Department of Treasury's Invoice Processing Platform. NAICS code is 334516, Analytical Laboratory Instrument Manufacturing; PSC is 6640, Laboratory Equipment and Supplies.
