DEXA InAlyzer2 – PIXImus Comparison
InAlyzer2 DEXA Systems Compared to the PIXImus System
The InAlyzer2 DEXA systems offer a well-tested technology for the measurement of bone mineral density and body composition in laboratory animals. The InAlyzer2 is as much as five times faster than the PIXImus, and the InAlyzer2 provides greater precision. A key InAlyzer2 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.| InAlyzer2 DEXA | Lunar Piximus | |
