minispec LF Series TD-NMR BCA Analyzer

Body Composition Analysis with Precision, Comfort, and Efficiency

The Bruker minispec LF Series is a trusted line of TD-NMR (Time-Domain Nuclear Magnetic Resonance) instruments optimized for non-invasive body composition analysis in preclinical and laboratory settings. Important parameters like Fat, Lean, and Free/Total Body Water can be determined in approximately 2 minutes without preparation procedures.

The minispec NMR Body Composition Analysis system allows repeated measurements throughout an animal’s lifespan. Animals can be measured daily, making it ideal for longitudinal studies.
