Ugo Basile Librae Incapacitance Tester

The Librae Incapacitance Tester by Ugo Basile has been designed to add speed and accuracy to weight distribution measurements in injured mice and rats. The device is used in osteoarthritis, bone cancer, nerve injury and post-operative pain research.

The device automatically records and compares differences in hind paw weight bearing for the assessment of spontaneous pain. Operator bias is thus reduced and trends can be monitored visually in real time.

The autostart feature identifies immobility windows, optimising test repeatability and saving operator time. The device is controlled quickly and seamlessly using a large colour touch screen.

Experiment data is displayed showing left/right weight and scatter charts and trend data. Recorded parameters include average paw weight, standard deviation, left/right ratio and more. Data is saved in universal .csv format for spreadsheets including Microsoft Excel.

The design is streamlined with no screws or protruding parts that could interfere with rodent comfort. Foot pads are easily removed and cleaned as they are conveniently attached magnetically. Quick calibration of high-quality force sensors (0.1 g resolution) is possible using the reference weight supplied.
