Bruker HP WB 73 A MAS 7DB CP BB VTN Solid NMR Probe 300 MHz

Used see photos.

HP High-power probe (built for solids RF loads/decoupling; you'll see "HP-WB" in solids literature)

WB Wide-bore magnet geometry (room-temp bore 89 mm; shim stack ID 73 mm)

73 A Fits the 73 mm shim system; "A" is the physical length variant for that magnet family (Bruker makes multiple length codes)

MAS Magic-angle spinning

7DB / 7 BL 7 mm rotor stator type: DB double-bearing; BL "boden-lager" (bottom-bearing)

CP Cross-polarization (usually ^1H → X to boost sensitivity)

BB Broadband X-channel (tunable over many nuclei; the "BB" channel)

VTN Variable-temperature–nitrogen style solids probe (VT gas is nitrogen; in VTN/WVT the bearing gas also carries VT). Contrast with DVT, where VT/drive/bearing are separate lines

7 mm Rotor diameter; sets sample volume & max spin rate class

300 MHz Nominal ^1H frequency of the target magnet (≈7.05 T); Bruker classifies probes by the ^1H freq

Broadband Multi-nuclear tuning/observe capability
