5MM 900 MHz Room Temperature Probe and installation to an existing Bruker NMR System

The National Institute of Standards and Technology (NIST) intends to negotiate with Bruker Biospin Corporation for the purchase of a 5mm 900 MHz Room Temperature Probe for an existing Bruker NMR System. The probe is needed by the Biomolecular Structure and Function (BSF) group in the Biomolecular Measurement Division of the Materials Measurement Laboratory at NIST. The BSF group advances novel measurement methods and models for the determination and analysis of the structure and function of biological macromolecules. The group needs a back-up room temperature probe for its aging 900MHz Bruker NMR system, which is currently underperforming. The primary probe is currently underperforming, and 50% downtime occurred in FY25, and 25% downtime is projected for the future due to ongoing maintenance issues. • The probe must be fully compatible with the existing Bruker 900 MHz AVANCE III NMR system. • The probe must be able to be controlled by the Bruker Topspin 3.7 software. • The acquisition is based on the need to purchase the Room temperature TXI probe. • The North American Industry Classification System (NAICS) code for this acquisition is 334516, Analytical Laboratory Instrument Manufacturing.
