Varian300

(Request for training)

The Varian Unity Plus 300 was installed in early 1995.  It is equipped with a wide bore Oxford superconducting magnet to accommodate probes for running solid state NMR experiments. It has two radiofrequency channels and is capable of broadband detection.  This instrument is used primarily for detection of heteronuclei such as 11B, 13C, 31P, 119Sn, and 195Pt, experiments that require long detection time, including dilute samples, and for two-dimensional experiments.  It has four probes: two 5-mm switchable broadband probes with boron-free glass insert, a 5-mm switchable inverse broadband probe, and a 7-mm magic angle probe for CP-MAS experiments.

  • Oxford  magnet (89 mm bore)
  • Sun Sparc 5 workstation 
  • 5mm switchable inverse broadband tunable for: 1H-19F/15N-31P with z-gradient
  • 5 mm switchable broadband probe with boron-free glass insert, tunable for: 1H-19F/15N-31P
  • 7 mm Magic Angle NMR probe for CP/MAS with variable temperature capability (-50º C to +100º C), tunable for: 15N-31P, spin rate up to 9.0 kHz
  • Variable temperature capability (-150º C to +200º C)
