The 900 US2 combines Bruker BioSpin's proprietary UltraShield and UltraStabilised technologies. The new instrument has been installed at the University of Illinois at Chicago specifically in the Department of Biochemistry and Molecular Genetics, for research on high molecular weight proteins.
"The 900 MHz magnet is essential for the high resolution and it ensures optimal performance of our TROSY experiments," commented Professor Peter Gettins of the University of Illinois at Chicago.
The 900 US2 magnet provides the highest field strength with a magnetic stray field that has only one tenth the volume and one fourth the footprint of a conventional, non-shielded 900 MHz magnet.
The 900 US2 magnet uses more superconducting wire and is about 30 per cent more expensive than an unshielded 900 MHz magnet. However, this increase in cost will be offset by significantly reduced facilities costs.
"The shielding technology, which greatly reduces the footprint, has dramatically increased the capacity of our NMR facility, allowing future expansion with additional instruments," he added.
The 900 US2 design enables it to fit in the same size cryostat as the conventional non-shielded 900 MHz magnets. Bruker BioSpin now offers US2 magnet models at two field strengths, 800 and 900 MHz in addition to a full line of UltraShield magnets from 300 to 700 MHz.
Combined with Bruker BioSpin's Avance NMR spectrometer they are ideal for structural biology applications.
