About this file
This is a Statement of Work (SOW) from the US Department of Agriculture for the purchase of Li-Cor gas analyzer components for the National Laboratory for Agriculture and the Environment.
The procurement involves two main items: one Li-Cor 8250-01 Extension Manifold and four additional Chamber Cable and Tubing Bundles (model 9982-056). The Extension Manifold features a sample volume of 27.9 cm³, operates across temperatures from -20 to 45°C with humidity tolerance up to 95% RH, and meets IEC IP55 weatherproof standards. It utilizes a diaphragm pump with a flow rate of approximately 2 to 3 liters per minute and communicates via full-duplex RS-422 communication at 115,200 baud with 24 VDC power input. Power requirements are supplied by the Li-8250 Multiplexer with typical 24V at 1.8A maximum, or an alternate input range of 21.9 to 25.5 VDC at 80W. Each Chamber Cable and Tubing Bundle is 15 meters in length with 30 meters of total tube length, 237.5 cm³ tube volume, and sealed power and data cable connectors designed for 8200-104/C Long-Term Chambers. The National Laboratory has used Li-Cor 8250 products since 2020; the extension manifold expands data collection capacity through a daisy-chain connection method. No government-furnished equipment, travel, security requirements, data rights restrictions, or Section 508 compliance requirements apply to this procurement. Contractors must be Li-Cor authorized distributors, with Li-Cor's direct contact information provided in the SOW.

Project Purchase of Li-Cor Gas Analyzer Components
General Information
1.0 Scope of Work
Provide a brief statement of the overall project, including goals and objectives.
Purchase Li-Cor 8250 Extension Manifold and (4) additional Chamber Cable and Tubing Bundles (9982-009).
2.0 Background
Provide a general description of the requirement, describing the acquisition history (if applicable), the current environment, and the vision of the future of the requirement. If information technology is a factor, provide pertinent technical facts.
The National Laboratory for Agriculture and the Environment has been using Li-Cor 8250 products extensively since 2020. The 8250 Extension manifold connects via a daisy chain method to other 8250’s to expand the number of gas analyzer chambers collecting data. The cable and tubing are specifically designed to work with the LI-8250 multiplexer using Li-Cor cable-and-tubing assemblies.
