The National Cancer Institute seeks to acquire one spectral flow cytometry system, including automation, software, and manufacturer-supported services, to replace an aging instrument and support advanced immune cell analysis for pediatric oncology research. The required system must feature full-spectrum detection, at least six excitation lasers, 51 fluorescent detectors, and acoustic-assisted hydrodynamic focusing, with compatibility for automated 96-well and 384-well plate loading. Delivery, installation, and training must be completed within 12 weeks after award at the NIH campus in Bethesda, MD. The contract will be a Firm-Fixed-Price Purchase Order, awarded based on best value considering technical acceptability, past performance, and price. No specific budget amount is provided in the description.
