Biospec 117 16 USR

The BioSpec 117/16 combines the advantages of ultra-high-field with the versatility of high-field preclinical MRI instruments. With the largest range of coils to enable extreme versatility at ultra-high-field for studies on mice and rats.

It is built with a zero-helium boil-off, nitrogen-free, Ultra Shielded and Refrigerated (USR) superconducting magnet for long service intervals and reduced maintenance costs. The pulse tube cryo-cooler technology utilized in this USR magnet greatly improves cryogenic efficiency and has the additional benefit of minimizing the vibration transfer to the magnet system, which is essential for optimal imaging performance.
