NMR Magnets

Magnet Choice for Every Application

JEOL offers a complete family of superconducting magnets including actively shielded magnets from 400-800 MHz, and ultra high-field magnets from 900-930 MHz. Manufactured to our specifications by Jastec, our magnets feature low cryogen consumption cryostats, extremely small B0 drift characteristics and excellent homogeneity. Both narrow and wide bore systems are available.

Space-saving design with a compact superconducting magnet

Greater flexibility of installation layout of the instrument is possible with the new compact magnets that have a smaller stray magnetic field.

* The required ceiling height = Total height + Current lead length or Transfer tube length

** These values are calculated from the filled capacity and the estimated evaporation rate, the actual number of days may vary depending on the actual use environment.

* These values are when the option is used.
