The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking vendors for a high radiance UV-NIR light source with a monochromator to support biotechnology research in gene therapy manufacturing. This procurement aims to acquire a light source that is crucial for measuring the refractive indices of nanoparticles used in light scattering microscopy and for characterizing individual nanoparticles with dark-field microscopy, with specific requirements for broadband spectral output from 350 nm to 1000 nm, monochromator integration, automated control, and software compatibility. Interested vendors are invited to submit detailed information about their products, including technical specifications, performance capabilities, business status, customer history, and any additional services such as installation and training. For further inquiries, vendors can contact Forest Crumpler at forest.crumpler@nist.gov, and they must ensure registration in the System for Award Management (SAM) to be eligible for future solicitations.
