Standard Bore Imaging Probe

Micro 5

The micro-imaging probe Micro 5 has been developed for applications with standard bore magnets (52 mm ID) for the investigation of small objects with diameters of < 1 mm to max. 10 mm.


The Micro 5 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.

Gradient System

Bruker’s Streamline gradient technology provides excellent active shielding and high efficiency for X, Y, Z gradients of 300 G/cm at 60 A current. The very low resistance (< 0.2 Ohms) minimizes internal heat dissipation, and with water cooling very high duty cycles can be employed with switching times down to 50 µs. A built-in temperature sensor and security circuits guarantee for safe and reliable operation. The internal diameter of the gradient system is 19 mm, and excellent linearity is achieved over a large volume (15-mm diam. sphere) so that quantitative image analyses as well as precise diffusion experiments can be performed.

The probe features a modular construction with exchangeable rf-inserts of various designs and variable temperature operation and control. The Micro 5 has a removable gradient system and uses the same body and electronics as the Diff 30 probe.

RF Section

The probe body is equipped with two independent rf-channels. The exchangeable rf-inserts are mounted on ceramic bases and are offered as single- or double-tuned units in two basic forms (horizontal solenoid or vertical Helmholtz) with various diameters.

In addition Coil-on-a-Chip inserts are available for this probe.

DIFF30 / DIFF50 Configurations

The Micro5 standard bore micro-imaging probe can be converted into a Diff30 standard bore z-diffusion probe or into a Diff50 wide bore z-diffusion probe, just by exchanging the plug in Micro5 gradient system ba a Diff30 or Diff50 gradient system. With the Diff30 configuration gradient strengths of up to 1800 G/cm are available. With the Diff50 configuration gradient strengths of up to 3000 G/cm are available.
