The Varian 400 MHz WB Premium Shielded magnet features outstanding fringe field containment to minimize laboratory space requirements. The 89 mm bore magnet features a larger homogeneous volume over the standard 54 mm product, giving greater flexibility for applications. External field perturbations are efficiently attenuated, and pneumatic anti-vibration support legs (supplied as standard) allow siting in a wide range of environments.
The Varian 400 MHz WB Premium Shielded magnet features an 89 mm bore and a Jarger homogeneous volume, offering flexibility for micro-imaging, liquid, and solid-state NMR applications. It includes outstanding fringe field containment and pneumatic anti-vibration support legs for efficient siting in various environments.
The system consists of a highly homogeneous superconducting magnet housed within a low-loss helium cryostat. Key specifications include a 400 MHz frequency, a 270-day helium refill interval, and a radial 5 Gauss stray field extending to 40 cm. The document also lists included components such as level probes, readout units, and transfer lines.
