The scope includes replacing and upgrading consoles, cryoplatforms, cryoprobes, and electronics, plus providing specific probes, with all components requiring compatibility with Bruker Topspin 5.0 or greater software. Performance will occur at the NIST NMR facility at the Institute for Bioscience and Biotechnology Research (IBBR). Delivery is required within 12 months after contractor receipt of order. No budget amount is specified.
