SX20-LED Stopped Flow System and associated components

The National Institutes of Health (NIH) – National Environmental Health Sciences (NIEHS) is conducting a Sources Sought market research to identify small‑business capability to supply an SX20‑LED Stopped‑Flow System with associated components for rapid kinetic and fluorescence/absorbance measurements. The instrument will support research on RNA processing, ribosome assembly, and viral RNA pathways, requiring millisecond‑scale mixing, high‑sensitivity detection, interchangeable low‑volume flow cells, and precise temperature control (‑20 °C to 60 °C). The acquisition is a one‑time, firm‑fixed‑price purchase that includes training and warranty support. Interested small businesses must submit a capability statement (max 7 pages) by the deadline. • Required product: SX20‑LED Stopped‑Flow System with LED excitation, fluorescence & absorbance modes, 20 µL/5 µL flow cells. • Performance specs: detection as fast as 0.1 ms, temperature range ‑20 °C to 60 °C, high‑sensitivity fluorescence. • Intended use: kinetic studies of RNA degradation, protein‑RNA complex formation, enzyme kinetics, etc. • Procurement type: Small‑business Sources Sought (market research) – not a formal solicitation. • Submission: capability statement via email to Luz Casey by 8:00 am EST, 16 Sep 2026. • Contract: firm‑fixed‑price, one‑time supply with training and warranty.
