Bruker BioSpec AV1 4.7 Tesla/40 cm
The 4.7 Tesla system has been the workhorse of the NMR Center. It was originally installed in 1986, and the imaging console has been continuously updated and is currently interfaced with a Bruker AVANCE AVI spectrometer driven by a LINUX workstation and Bruker ParaVision 5.1 imaging software.
System Features
Four receiver channels
Two RF transmitter channels
1 kW RF amplifier
Copely 200A/300V gradient amplifiers
Actively Shielded Gradient Sets
30 cm diameter Magnex gradient set (40 mT/m, 250 μs risetime)

Bruker AVANCE 500WB 11.7 Tesla/8.9 cm
 The 11.7 Tesla system has a vertical 89 mm actively shielded superconducting magnet. The magnet is interfaced to a Bruker AVANCE DRX spectrometer driven by a LINUX workstation and Bruker ParaVision 4.0 imaging software.
The system has a micro gradient set with a maximum gradient strength of 1000 mT/m and has a wide variety of RF probes for imaging fixed samples as wells as mice and rats in vivo.

The Bruker MiniSpec is available for routine relaxation measurements. The instrument consists of 10 cm and 18 cm RF probes, a temperature controller, a 300W RF amplifier and software for fully automated determination of T1 and T2 relaxation times in tissue samples, cell suspensions, and contrast agents.
The NMR Center has access to four high resolution Bruker AVANCE DRX NMR spectrometers. The magnetic field strengths correspond to proton resonance frequencies of 300 MHz, 500 MHz and 600 MHz. These instruments have four RF channels and are routinely used for high resolution protein NMR spectroscopy and NMR spectroscopy of Biological samples and metabolites.
