The Varian Inova 500 is a three channel broadband system equipped with tri-axis pulsed field gradients and variable temperature control with extended duration heat exchanger. The system's probes include:

• Varian 5mm HCX triple resonance probe with triaxis gradient coils.  The "X" channel covers the NMR frequency range that includes ³¹P through ¹⁵N.

• Nalorac 5mm triaxis gradient indirect detection: broadband decoupler channel covers the NMR frequency range that includes ³¹P through ¹⁵N.
  
• Varian 5mm z-axis gradient indirect detection: broadband decoupler channel covers the NMR frequency range that includes ³¹P through ¹⁵N.
  
• Varian 5mm indirect detection: broadband decoupler channel covers the NMR frequency range that includes ³¹P through ¹⁵N.
  
• Varian 5mm broadband: broadband channel covers the NMR frequency range that includes ³¹P through ¹⁵N.
  
• Varian 10mm broadband: broadband channel covers the NMR frequency range that includes ³¹P through ¹⁵N.
  
• Doty 4mm XC-MAS probe for solids.
