MR Microscopy standard bore probe with exchangeable coils and integrated gradients for samples up to 10mm diamater.

Microscopy images with resolutions < 10 x 10 x 10 μm3 samples in a Bruker standard bore magnet. But the probe can also be used in wide bore and super wide bore systems. Combined with it‘s versatile exchangeable rf coils it can be adapted to perfectly match your application, supporting sample diameters from 0.5 -10 mm.

The Micro5 probe can also be used as a 3-axis diffusion probe or combined to increase the gradient strength in one direction. It is particularly useful to investigate anisotropic diffusion.

The Micro5 probe is typically used to study mineral or geologic samples, polymers, tablet dissolution kinetics, plants and seeds, bone or tissue biopsy samples, and small insects.


Rf coils are exchangeable, the gradient coil must be unmounted first to allow the change of the rf coil.

  • 1 mm MicroCoil (coil diameter 1 mm, max. sample size 500 μm). To replace the sample the probe must be removed from the magnet as with the solenoid coils, unless e.g. a Flow Cell is used. Different Type of sample containers are supported
  • 2-4 mm Solenoid coil. The samples must be placed horizontally in this type of rf coils. This requires to remove the probe from the magnet, remove the gradient coil and place to sample.
  • 5 or 10 mm single tuned saddle coil or a 5 or 8 mm double tuned coil. In this case the sample can be changed using the Bruker BST sample transfer system, the probe remains inside the magnet.
  • Diff Software Application
  • Dynamic Center for data processing
