DEXA InAlyzer – Piximus Comparison

InAlyzer DEXA Systems Compared to the PIXImus System

The DEXA InAlyzer offers a well-tested technology for the measurement of bone mineral density and body composition in laboratory animals. The InAlyzer DEXA systems are as much as five times faster than the PIXImus, and the InAlyzer provides greater precision. A key InAlyzer benefit is the option to handle lab animals as large as 3000 grams, while the PIXImus is limited to 50 grams. The chart below details the two systems.
