Incapacitance tester Librae - for mice and rats

Code 47882/47883/47885

Measures the weight distribution difference between an injured and unaffected hind paw of a mouse or rat. For the assessment of spontaneous pain in osteoarthritis, bone cancer, nerve injury and post-operative pain studies. Automatic operation reduces operator bias, optimizes repeatability and saves time. Easy to set up. Data visualization to monitor trends. Fast and easy cleaning procedures.

Features
  • Measures hind paw weight distribution, through the most widely used method (>1,500 citations).
  • Equipped with the latest technologies by Ugo Basile.

Automated, efficient, accurate

  • Automation of the measurement process using AutoStart, a unique feature that identifies immobility windows to optimise test repeatability and save operator time.
  • Option to switch to manual mode with the included foot pedal for hands free operation.
  • Quick calibration of high quality, precision force sensors (0.1g resolution) using the reference weight supplied.
  • Quick, seamless management of settings and data using large, bright, colour touch screen.
  • Visualization of test data as left/right weight histograms and scatter charts displaying 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. Easy transfer of data using supplied USB key. 
  • No screws or protruding parts that can cause interference with the rodents and possibly compromise experiment results. 
  • Fast cleaning of foot pads (within seconds) because they are conveniently attached magnetically for easy removal.

Features&benefits of incapacitance tester Librae

  • Measure hind paw weight distribution: through the most widely used method (>1,500 citations), now updated and equipped with the latest technologies by Ugo Basile.
  • Autostart is a unique feature: automate the measurement process by identifying immobility windows.
  • Touch screen and USB data storage: let scientists setting, controlling and managing instrument data quickly and seamlessly. Through a few, intuitive buttons, one can reach all the functionalities. The included USB key stores all data for optimal portability (average paw weight, Standard Deviation, Left/Right ratio, etc.). The Left/Right weight histograms and scatter charts display on line the experiment output for an immediate visual control, graphically effective and easy to follow during the test.
  • Reliable and easy to collect results:, software included: high quality force sensors (0.1 g resolution) are easily calibrated with the provided reference weight and show no screws or other parts potentially interfering with the animal, for maximum experiment repeatability. After each test the result can be stored or discarded and data can be transferred from the instrument to a PC for MS Excel.
  • At the end of the experiment the foot pads can be cleaned in a few seconds, being magnetically attached to the base.
